Why is something that obviously should well be evolutionarily wiped out (if it is indeed due to genes/people can't help it) not, by now?
(Corollary question if you say "there is no evolution, it's intelligent design" - ok then what the heck purpose would homosexuality serve in this design? Honest question, I'm not being a smartass.)
Edit - PS you know you're over some kind of target if an OP gets downpoots.
Dolphins and swans are fags too, a couple of monkeys like Bonobos and Macaques (kek) also fuck same sex, even some lions. However the BIG difference here is that these animals don't drive cars and get library cards or homeowners insurance. I would throw adoption in there too but the homo swans actually do that.
Edit: To the faggots whom it may concern: Everything I wrote is a fact. Dolphins, primates, birds - whatever, all have homosexual relationships. You can send me as many nasty PMs as you want but it doesn't change FACTS ya big homo.
The swans bit is pretty amazing actually.
