there really is no reason for anybody to dislike gays/lesbians.
they are people too.
and if you are going off of the religious standpoint, the bible may say that homosexuality is a sin, (though in my opinion all religion was just made up way back when to give people hope so they were less scared of death, if people thought there was nothing after their life here on earth. what would they live for?... religion is a bunch of bullshit in itself.)... however, the bible does also say 'no sin is greater than another' as well as 'don't hate your neighbor'.
so fuck you all who use your stupid religion as a reason for your self doubt about your own sexuality. they are no different from you, asshats.
but we always can't stop hatred when it's part of human nature.
