The above poster is either a troll or so rude and far flung from empathy that I don't even think it's worth responding to. The first quote and response is a straw man. The second is disturbing in that you think you are qualified to make such a judgement. If others actually feel insulted by my post, let me know how and why so I can learn.
He's not a troll. And it's not an offensive attack against furries.
Anyway, the term "furry lifestyler" has been stolen by certain...undesirable people. You know, the people who like murrsuits, think zoophilia is a-ok, and like to give asspats to sexual deviants, who may also be criminals. It's like the term otaku. Sure, you might like anime a lot, but there are some people who use that term for themselves and think "when they go to Japan" all the women will worship their anime knowledge.
Frankly, association with a single group should not form a person's identity. Rather, what the person does in the group should define them. I could say "Oh, since I have an engineering major, this means I'm an engineer". Nope. You have to be employed first. That is doing something with what you have or who you are. Sure, you're probably trying to be unique, but when all you have is just association with a group, what differentiates you from other people in the group? As a furry, how are you different than me? Besides your fursona.
What perhaps gets people annoyed with lifestylers is a feeling that they are too excited about being a furry, and feel the need to talk about it, always. It's like the stereotypical brony or otaku. Too overwhelming sometimes. And then there's the victim complex and the "hugbox". That, and the rest of the geek social fallacies are the reasons why people get annoyed by furries. Not the porn, it's the reaction to trolling. Trolling is just joking around.
So please, to all furries out there, please stop with the geek fallacies. The fandom could be great, as there isn't a single canon or medium to latch onto. There's so much room for creativity. But the geek fallacies get in the way. So please furries, please grow a backbone. Or at least realize that the people who "troll" you are usually hardcore otaku, who are in the same boat as you.
As for the otherkin stuff, it's just New Age weirdness combined with possible induced psychosis for entertainment. Like Pony Tulpas. At least it isn't otakukin. Well, as long as you aren't making money by telling people that you can contact their deceased relatives and reveal said relatives' thoughts about your customers, it's not hurting anyone.
