Ah, so apparently the only thing wrong with Homosexuality is that the "only argument against it" is Christianity. What about the fact that it is abnormal? If Homosexuality is legal, under that line of thinking, so should Bestiality, Necrophillia, etc.

They are all sexual perversions. If we legalise one of them, then wouldn't the next logical step be to legalise all of them? Oh, wait. Abnormal/perverse sexuality is considered largely "Wrong", but it is perfectly fine for the ones which are considered "Okay" (Homosexuality, Transexuality, etc) primarily based on the fact that they are a "civil rights" group, and therefore have sympathy for their cause.

So whenever someone says "Christians really need to stop being bigots ("Bigotry" being a meaningless buzzword which doesn't actually mean anything) and accept people can be gay", it's quite likely they'd be supporting other forms of deviancy if they were classified as an "oppressed group". So remember, if you ever see a "Gay Pride" parade or whatever, just remember it could very-well be supporting some other form of abnormal sexuality which we see as "perverse", if they pulled the victim card by saying they were being "persecuted".

TL;DR Version: You're hypocritical morons who don't realise that if some other sexual perversion was pulling "Pride" shams and other forms of attempt at "normalisation", you'd all be pushing congress to allow people to marry animals, or dead bodies.
