It could be argued that Homosexuality is comparable to other non standard sexualities, and so should be treated as such. Claiming that, if we society as a whole was to promote acceptance of homosexuality, would it be fair to still demonise other non standard sexual tastes?
Necrophilia, zoophilia and paedophilia are all what can be considered non standard, but widely unacceptable practices. In the same countries that ban homosexuality, these are banned as well. This isn't to say that I approve of anyone partakeing in any of these, but it makes it easy to understand how people can believe homosexuality is morally unacceptable, as it is viewed in the same light as those mentioned above. So, if you believe that acting out your sexual desires is a bad thing, then surely all should be discriminated against equally.
Of course this doesn't take into account age of consent and is disregarding the act of rape entirely.
