Lets see...
I'm straight, and I don't wanna love on wolves.
That's one of the most insulting things anyone could do to my favorite animal!
Its called the furry fandom. Its not an organization, just people who are interested in anthro animals.
Just like non-furs, not all furs watch porn, and not all of them are gay.
That's not what furrys are about. Its about RPing, writing stories, and drawing your fursona (Anthro Character) and just having a good time with people who share your interests. Fursuiting is just like cosplaying for anime fans, its about their favorite character, and its all for the fun of it.
Now, I'm not gonna sit here and lie to you saying that not ALL furs are clean and not watch porn, or do things to that extent, but so do non furs, and they don't gent nearly as much lip for doing it. If all stereotypes were true, then every middle aged white guy is a child molester, and I'd be as far away from them as possible.
The people who really want to be/are their animals are called otherkin.
