I don't think anyone here condones bullying. The guy who made the video just wants you to get riled up like this so he can point to everyone and say, "See! This proves my point!", all the while growing an audience. The best way to deal with Internet trolls is not to feed them but if you feel the need to engage, then I suggest calmly refuting the arguments and stay polite and civilized so THEY look like the crazy ones.
I've been around message boards for a long time and I've moderated some infamously contentious ones. I see this kind of thing all the time.
Yeah there no point with arguing those online types. Who have no idea that there views are either wrong or downright stupid, Have no room for any change. Most forums were horrid for that, They would just ban you if called out there views on furries or just resort to insults with no maturity.
