I've heard preachers preach on the sin of homosexuality. Some might even say homosexuals are going to Hell, gays are going to Hell, lesbians are going to Hell, etc.
When I grew up, the way 'homosexual', 'gay', etc. was used was to refer to people who did 'gay stuff'-- meaning sexual acts. So I thought.
It turns out based on the original meaning of the word and the way it is used in academia, a homosexual is someone attracted to the same sex. Now suppose you are a young person and you've never done any 'gay stuff', but you found yourself attracted to the same sex. Then you go to church, and you hear someone preach that if you have same-sex attraction, you are a sinner and you are going to Hell.
The sins that homosexuals commit that are related to homosexuality are things like actually performing same-sex sexual acts, and looking with lust. Having attraction for the same sex is a bad thing to have to deal with. But can't someone who struggles with this still be a Christian and just resist temptation?
Many of us men are attracted to beautiful women. Especially when we are/were young, a beautiful scantily clad woman might be a bit of an eye magnet for the flesh, but you can choose to avert your eyes and discipline your mind and not sin. There are ads on magazines and various other type of media. There is a difference between what we find attractive and the acts we commit. If a woman is attractive to a man, that doesn't mean he has committed fornication or adultery with her or that he has looked at her with lust.
And if a man struggles with same-sex attraction, that doesn't mean he constantly goes around sinning. At least with the Gen-Y and Gen-Z generations, and probably most of X now, and in academia, and certainly with LGBTI folks, in the US, 'gay', 'homosexual', and 'lesbian' refer to 'orientation'-- not what they do with their sex lives. Some Fundamentalists preachers who say 'Homosexuals are going to Hell' do no realize that what they are saying from the perspective of the listener is if you find yourself attracted to the same sex, even if you don't act on it, you are going to Hell. It sounds rather hopeless.
We do need to combat the ideas associated with 'orientation' that these types of inclinations or lusts are permanent problems. LBGT folks think of their sexual inclinations and propensities to be attracted as a big part of their identity. But the Bible tells Christians, to "reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord." (Romans 6:11.)
Christian men who are attracted to women do not introduce themselves as "I am a Christian who has the propensity to fornicate with women", and so Christian men who struggle with same-sex attraction should not say, "I am a gay Christian." We should reckon ourselves dead to sin, and alive to God, and "make no provision for the flesh to fulfill the lusts thereof."
Some people with same-sex attraction who become Christians may have to constantly struggle against it and overcome it for years, like some men have to tame their eyes. Others may be delivered from the temptation and not worry about it. Marriage between a man and a woman is a Biblical remedy for decreasing the propensity to be tempted by sexual lust.
