text: Homosexuality at its core is not sustainable socially or biologically.  I am a christian and I won't even make a christian argument.  Two men cannot breed and reproduce and neither can two women.  Biologically this has to be a lifestyle choice because this behavior would be weeded out in the long run just by not being able to reproduce.  You cannot have a male body and be born female.  Males have certain parts and traits, females have certain parts and traits.  You can be a man and want to act like a woman, which is a lifestyle trait, nothing more.
