Homosexuals are biologically worthless, simply because while they have the ABILITY to reproduce, they choose not to due to their disliking of women. This is not a bad thing though. There is plenty of straight/bisexual people that will reproduce with women they find attractive. The only way a homosexual would be biologically useful, is if he forced himself to look past the woman's appearance and focus on her personality, and the need to have a family of his own blood. But then again, that would make him a Pansexual (someone who doesn't care about the gender or appearance of a person, but only emotional aspects/personality)
