Just re-read your post, and maybe I can help you a little more here.
Reactions to homosexuality in the Christian community vary, but there is a very large group of those who believe it's a sin. There's a lot of variance in this group--there are some attention-seeking factions who say that God hates homosexuals and that everything bad that ever happened in the history of the world is due to the fact that we don't stone homosexuals to death like the bible says.
These are a very small minority of people, and they do not represent even most evangelical conservatives.
Many who believe it's a sin also believe homosexuality is a choice that individuals make regarding sexuality, or a disorder of some sort. Current psychiatric literature disputes this opinion, but there are still Christian sects out there who try and "cure" gay people of their orientation. Such programs have been shown not to work--the co-founders of one such "ex-gay" movement ended off running off with each other.
The reactions of people to anything they don't understand, whether it's homosexuality or hip-hop music, vary widely with personality, but the underlying emotion is always fear. We're hard-wired, I believe, to fear that which we do not know or understand. (If you don't believe me, try feeding a child a new food...) Many people over-react to fear with anger and hatred. Others react by withdrawing. I've lost some very good friends, and even a job, when I "came out." Others, after a time, will react with curiosity and a genuine will to know more.
When writing about Christians and homosexuality, you have to realize that many, if not most people are largely ignorant, not only of the theology behind gay and lesbian liberation theology, but of basic biology, and basic Christian theology. My own credentials are somewhat different than average--I have a BA with emphasis in Psychology, especially in issues relating to this subject, and a Master of Divinity and a Master of Pastoral Studies, with courses in sexual ethics, liberation theology, and biblical history and interpretation.
