I went to a Bible College a few years ago, and wrote an essay about Gay Christians. I believe I did a good job, but because I reached a different conclusion than is commonly accepted, I wasn't graded highly for my efforts... and I am straight). Nothing in this post is taken from my essay though; I wrote this quickly so sorry if it's not well-written.
When I get the chance I will find it and post some links to a website you may find helpful. It contains a pro-gay article written by a heterosexual Christian minister exploring mistranslations in the Bible that cause people to believe that being a homosexual is an abomination. (I can't vouch for the accuracy of his teachings as I do not understand the original languages of the Bible, but it seems to make sense to me.)
There are 4 main attitudes of Christians towards gays:
1. "God Hates Fags". These "Christians" are hateful towards not just homosexuality but also homosexuals themselves. Their attitude is that homosexuality is a sin, and the sinners are going to hell; good riddance.
(I hope everyone here is as disgusted by that as me)
2. "Hate the sin, not the sinner". It's a sin, but not a "worse" sin than lying, stealing, etc. This attitude is more "tolerant". Most Christians probably fall in this category. (I have no proof, but it's what it seems like to me personally). They feel this way because it's how thay have been taught; it's how their Bibles have been translated, and they believe it because to them it is the Word of God. Many believe that homosexuality is an affliction that can be "cured" through God's love. (Which may be possible for some people because they may be straight but turn to relationships with the same sex due to some kind of traumatic experience with the opposite sex, and so if their pain is healed, then so is the "homosexuality" because they can now have a healthy relationship with the opposite gender again. People in this category usually don't believe that a person can be inherently homosexual, and that homosexuality can be a natural preference that will develop within a person without being a case of cause and effect.)
3. "It's OK to be gay.... just don't have sex". Some Christians believe that it's not a sin to be homosexual, but it is a sin to act on it, ie. have sexual relations even within a marriage-like partership.
4. "It's okay". This is probably not a large percentage, but some Christians believe that homosexuality is not an illness or affliction, but it is something that a person is born with, and if God made a person that way, then it is not a sin to be homosexual, and sex within a loving, comitted union is acceptable. They believe that passages in the Bible concerning homosexuality are either mistranslated, or don't matter because many of the rules in the Bible are seen as irrelavent (such as the aforementioned scriptures concerning seafood and clothing.)
There are probably more viewpoints but I think these are the main attitudes. My point is that not all Christians think or feel the same. You don't have to think or feel the same as Christian X, Y or Z either.
Please stay strong. Much of what Christians are expected to follow, and much of what they judge other people over, is not even in the Bible. Many "laws" are man-made, not set by God/Jesus. Pray for discernment, so that you may grow strong in your faith and be able to work out yourself (but with God's guidance) what is right and wrong for YOU. There will always be people who will look down on you (not only you, but every single person) for whatever reason, and will tell you that you are wrong in some way, but if you have a strong relationship with God, then it is His opinion and your own opinion of yourself that matters.
I hope this helps
