The Bible mentions a lot of things that no longer have any validity. Besides the Bible is just a story book written by mortal men. Isn't it just possible that they could have included some of their own prejudice?
I dont feel like typing the many parts of it, the History that has been proven to be true. But of course, people may think what they will, That is where free will comes in.

the only thing the bible says about gay sex that i can remember is it says dont do it. I dont remember anything in the bible where it says anything else. Any punshiment, etc, is man made. In this case as in many others,
it is not humans job to judge. But like many on both sides of faith debate,
they do seem to forget that part.
