We litteraly have brain scans of the human brain indicating that trans people have the brain of the opposite gender in a body that produces the wrong hormones for that brain, resulting in dysphoria and mental health problems unless they receive at minimum hormone treatment to match their hormones to their brain. We don't live in a fantasy world where nuerology doesn't exist.

The aids epidemic came about because condoms wheren't a thing in the gay community. Sex ed back then was backwards as hell, and in some cases still is. Because Gay people didn't have to worry about pregnancy, they didn't use condoms that often. And when aids hit that community that wasn't using condoms by the same coincidence as straights, the results where to be expected.
Respectability politics is litteraly political correctness, and doesn't actually work.
People who don't transition who are trans suffer from a pile of mental health issues due to their brains being at odds with their bodies. They are more likely to commit suicide as a result.
I don't actually see a lot of "kill all cis" memes from the far left. I did see a gay man drive through a protest of the death of a transgendered woman at the hands of police. It's nice to see now that Gay people have their rights they are leaving everyone else out to fight that struggle themselves.
My best friend is a transgendered woman. She grew up going to a church that denounced her as evil and deffective, with a father that advocated conversion therapy and stockpiled arms for the "coming race war". The last time she attempted suicide was before she started to transition. Since starting hormones, she has been impressively more mentally stable. She used to be on testosterone overload, which made her a violent asshole. She still has mental health problems because of the bullshit she was subjected to, and will probably carry some of those mental scars for the rest of her life.
Lets start this from the top.
1. The link your provided is just a news article, not from a trusted and non biased scientific/medical organization. Its really an echo chamber of "trans brains are like this" and mentions nothing new or neutral, in fact its more sounding in support of trans people via a lie of "they are like this due to brains and nothing else". That's not true, they are sick, very very sick and unstable people.
2. We have to start with the the origins of the LGBTQAI+, it was founded by a black trans person that after their revolution was done and said spiraled out into horrific portions. While such person created it, they never took responsibility or common sense into account. And yes while the queer folks dont use condoms its because...We cant get members of our same gender pregnant, that's a fact. So after the volatile queer culture went back into sex with actual function and no real consequences no one took accountability for anything. That trans person who created it all? Did nothing to convenience others to use safe safe methods, to stop foolish and destructive behavior that to this day is still stigmatizing queer folk.
I dont think thats insane to say, the leader did nothing to try and change, save lives and ended up creating and entire faction that Bloomed the worst virus epidemic in this country since say...the spanish flu. Infected queer folk spread out into the worlds domains, donating blood, sharing needles. They brought this on themselves for not taking control and thinking about anything other then sex, drugs and partying (which to this day is still true!) So now its not just a gay issue, its everyone issues. There is a risk for the virus always due to people not being safe, logical, using common sense. The same traits of the LGBTQAI are still to this day found: Culture without purpose that leads to horrible things. Now the thing about the AIDS crisis is that it was created and spread by active parties in LGBTQAI, that means trans folks too. Frankly I think any group that doesn't take any decent responsibility for basic health and going all in is a threat.
Now to #3. Trans people who do transition still are at risk of mental health, just because someone lives a lie, has their genitals cut off and take hormones doesnt make them what they want. In fact they seem to be more violtile and dangerous. A common exmaple would be Bruce Jenner. Made threats of violence on Ben Shapiro, and killed someone via a car. Transiting doesn't help people, getting therapy to undo their gender dysphoria does.
You mentioned the police thing: Since you didnt mention any other facts about what I assume you think is an unjust police killing (like everyone screams about everyday) I have to remind people that we don't live in a police state and police use force against threats. And frankly yes, people do have to things for themselves, fight and always have their rights upheld, know how things work in the law, in court and in life and death. We dont give things out for free, people have to work hard, plan and aquire things naturally. This is not a communist state where everything is given out and no work has to happen, we are on our own as adults but have a system of legal and social functions to help cater and solve issues we may run into with. Franlly I find it immature you think we homosexuals have to be slaves to everyone else's issues and problems. You see that's real political correctness the left pushes these "utopia freedom fighters" when they dont exist. Gays don't have to support other gays, bisexuals or trans people. We are free unique people, where are ideological plantation slaves. We don't serve only "our people" but society.
Your on your own, It is not my job to help other gays or people because that's not the law, that's not common sense, its a free for all which is what makes this country so great: Because I don't have to be your slave, or servant if you have an issue. That's what freedom is, an Independence from factions or ideas that want to control and have others serve only them.
Okay so how does that work? Churches are moral and religious codes of life conduct, having the freedom to presume religion and chose what you live and belief as is the greatest strength we have in this country. No one is a slave for just one idea, we have the professional choice to chose and be what we want ideologically speaking without the fear of the death or torture. Now I cant say that of islam, it is the number 1 killer of the LGBTQAI, muslim's and other religions, but here people are safe even if they live a lie that ends up killing them. Their life and well being and choices is their responsibility. This is not a government hand out nation.
And now heres the thing, churches have the right to say that. Its the biggest thing we have in america, Freedom of speech is its own checks and balances. Is it wrong? I am not sure because I haven't heard what the church really is worried about you mention, I have to get more facts to understand why they are coming from such a strong stance. But they do have a few truths in what you said, it is a social negligence, to parade around as something your not, in the opposite genders clothing and behave a certain way. Queer folk back in the day where indeed social outcasts because the never really added to society. Religion is building block of society, philosophy and morals, and such things where indeed a threat. You see if you don't keep balance and moral stance on things whats to stop hundreds of school kids from wearing the wrong clothing, acting like the wrong gender and destroying aspects of a stable society.
Now what worries me is what I have stated and hinted up above before. Hormone usage, using steroids just to feel "more intune" really sounds like addiction. This person of yours you know is not the right gender. Women should not need to take a sex hormone only found more in men that leads to muscle mass, violent tempers and if taken to much leads to cancer, heart issues and so forth. More and more this sounds like a drug addict, needing some supply of something to remain what they are...but this person you know...isnt the gender they are even with all the drugs they take. Its not hateful to say that.
Frankly I'm more worried people like you are okay with trans people taking hormonal drugs, and ignoring the reality that they aren't the gender they are. They cant have kids the way they think the real gender they have is naturally. Sex is a very important thing, its an identification of who we are naturally as humans, and when you change that you are creating something false, that doesn't exist, and kills people because it is an illness. You cannot treat an illness by feeding it lies. That makes all illnesses worse. People with gender dysphoria are dying at their own hands because people have been catering to lies. That is not okay at all.
