reproducing is not the only way to see to it that your genes are represented in the next generation
I think someone needs some 1st grade science education

Another point, A species with 0% homosexuals will flourish more than a scoiety with homosexuals using up resources but not contributing to the next generation.

To the guy who said anyone can get pleasure from gay sex, well to enjoy sex you need to be aroused, and most people don't get aroudes by the same sex.

Everyone seems to be missing the point that in the case of gay men, their father passed on his hetrosexual genes, yet his son turned out gay. If a set of parents are both 179cm and their child is 179.1cm tall, that is a minor deviation that is not to be considered a major medical abnormality, almost no difference at all, but to go from hetrosexual to homosexual in a single generation is a massive change, and clearly shows that something major has happened along the path.
