You said: I believe they were born with a tendency to be gay. That's why so many of them became preists and nuns...they knew they were different...and believed God made them that way. I do not believe it's a CHoice. You are either attracted to the opposite sex or you're not....it is not a choice.
I agree, our tendencies and desires may not be a choice. I have the tendency, desire and inclination to fondle almost all attractive women I see, but restrain myself (and if I didn't my wife would). The fact that we have these tendencies as biological characteristics does not excuse them nor make them acceptable.
All I am saying is that I believe many of them were born attracted to the same sex. I didn't mention my opinion of accepting it or excusing it. Although......I do not want them to be able to marry (religiously).
