"The people that born like gay , is by behavior in the last life before this . "
Who says they born like gay? Any evidence? Prove it.
And who coined the "homophobia" term? (relax I know)
eg. almost people even don't know what represent "Antisemitism" ( right now there are more then 7 nations which spoke semitic language including arabs)

As an evolutionist and biologist I can't accept homosexuality as something normal, ....1500 species bla bla? yeahh and my dog sometimes is climbing up on my neck.. What represent the sexuality in nature? pleasure? wrong!
