@kasimax Do you think the idea is ridiculous that someone can be born to prefer the same sex, just as someone can be born with a penchant towards other inclinations?
Example, Mary is very kind and nice, but she has an addiction to alcohol. Joseph has no addiction to alcohol, but he's a chronic liar. Samuel, while having no additions or lying issues, struggles with depression and suicide.
So there is a massive spectrum of naturally born behaviors and tendencies. I can see no reason why a Christian should not freely admit that being gay, and born towards that orientation, would be a deal breaker.
However, the Bible is clear that just because a person is born with the make-up towards X, Y, or Z, does not make it OK with God (clearly stated in the Book many, many times). Just like not lying, stealing, sleeping around, etc, is also stated in the same manner.
