For some it is and for others it isn't. TYhose claiming to be Christians will mostly go by what the bible says, and strongly the New Testament. But, they don't consider that the people who wrote the book were not understanding in the sciences, and in this case, psychology. Imagine trying to explain to an apostle what hormones are. I'm reasonably sure that if they had the understandings we have today they would have a change of opinion.
In my study of this with others like questions came up. For instance- when Armageddon takes place will homosexuals make it through (survive it). A= yes. The event takes place after governments have been ended and people are free to do and become as they want, bringing in the actual end (die off)of the 3rd Generation, which in biblical terms is the actual ending event. Armageddon is the ending of evil people and the others remain. A Homosexual can be a good person just as anyone else. There's a catch---for everyone in that, the remaining will have to have given up recognizing the physical (seen as the carnal mind) as the person, and recognized as the spiritual, or mental. Homosexuals may have a harder time with the idea, depending upon the individual.
