Okay, but realistically, there are a few good reasons. Furry tends to pick up the kids who are counterculture for the sake of being counterculture. Most new members of furry are still working through high school, which is an arena where it's way easier to find a heterosexual relationship. Kids strike out with the girls a couple times or have a bad relationship, they decide to swear off females and join the radical/intellectual/oh-so-superior and open-minded cult of the homo. It makes you different, you know, and special. Like being a raver or atheist. And there are thousands more out there on the Internet who'll tell them just how special they all are together. Many gay furries are virgins, thus their sexuality is honestly somewhat null. This group is the one that hasn't really met any furries IRL but would really like to because man, they are so in tune and honest.
In other cases... when a furry joins the average community someone pretty quickly asks him if he's gay. If he answers negative the others will peer pressure peer pressure if you were gay we could be really close friends, snuggles, scritches. Okay, the furry decides he kind of likes being hugged and ooh that grope felt nice, he decides that maybe he is a naughty boy, hee hee a little alcohol, and it just naturally wanders into getting fucked. He then might seek out more of the same attention and encourage others to claim homosexuality. I don't believe many furries are subconsciously desperate and feeling I MUST FUCK SOMETHING, ANYTHING. They're just led on by people who are already gay and far too friendly. This is the group that has been social with real furries for quite some time, gone to conventions and all.
And the preponderance of pretend homosexuality in art and games, hell, that's just people thinking it doesn't mean anything (it doesn't) to have a character drawn gay with a buddy's or to roleplay out a gay relationship. To them it all just means more friends and more popularity, yay!
