Well, being a homosexual myself, I'm willing to say I am very biased towards it being right.
However, by the Christan ruling it is wrong.
Sex outside marriage is wrong by Christian law is it not?
Marriage is exclusively for man and woman according to the bible is it not?
So, I'm willing to accept that in the eyes of god I am a terrible terrible person, but hey, letting your self esteem be governed by one person, however almighty, doesn't seem like a good idea.
All that stuff about devil pacts was just silly, unhelpful and makes life as part of this minority harder to deal with.
I think that homosexuality is ok. However I don't think the 'public' gay community acts remotely respectful towards other people. There is no need for these huge parades, I suppose that they might be seen as a 'coming out' thing, but I don't agree with the public display.
Moving on
There is no choice about being gay. And those that would choose it are brave, I wouldn't have chosen it given the way the word gay is used in general public (which strengthens the negativity around it, which is starting to diminish where I am)
Also, we've had alot of religious arguments, and that word has been thrown around alot in this topic. Most 'ancient' cultures though homosexuality and intersex were the best things since sliced bread. Man being wit man in greek society was though to be good, preferred to even when compared with heterosexuality.
My buddist theory is shaky, but I believe there is something similar in that, although I am happy to be proved wrong there is anyone says other wise.
In japan there has been large amounts of change to weather it's right or not, going from accepted to death for it.
The dark ages really stuffed up acceptance of homosexuality though, more info should be coming soon with that.
