There are many denominations that LARP as Christian, Jew, or Muslim while advocating for gay rights, but they accomplish this by discarding large parts of their holy texts.
[1] For purposes of this discussion when I say "choose to be homosexual" I mean to choose to perform homosexual acts, get married to someone of the same sex, etc. I don't mean it in the sense of whether or not feeling homosexual desire is a choice.
- One could believe that, by making man in his own image, God desired that men be able to make their own decisions even if those decisions sometimes displeases him and/or they will eventually answer for.
- One could believe that a free society ultimately allows one to better accomplish God's will even if it also means that people are free to do things that you don't agree with.
- One could feel that, since humans are imperfect, it is possible that they will misinterpret scripture or apply it unjustly. Therefore, it may not be safe to force people to follow a given way of life.
- One could feel that judgement is the sole domain of God and therefore human law should not seek to enforce purely moral issues.
When I say that being against gay rights is an immoral position, it does not mean that a person is immoral, because that is an ill-defined phrase. It means that in the context of their speech and actions on the topic of gay rights, they are behaving immorally.
I agree that there is a spectrum of beliefs, and that it is necessary to meet somebody where they are. Each step is an important one, and beliefs change slowly.
Where I grow angry is when it is implied that Christianity is inherently and irrevocably against gay rights. Where I grow angry is when it is implied that all Christians must be similarly against gay rights. Where I grow angry is when it is implied that my faith must be a tool for bigotry, rather than an instrument of community.
