"Homosexuals cannot procreate and therefore are an evolutionary branch to be avoided."
Homosexuals sometimes do procreate. I personally know several. Other than that I agree with you. Homosexuality has the net effect of ending the genetic passing of a family line. This may be a natural way of removing a series of traits that are developing an unnatural path.
You mean...a woman can make another woman pregnant???? [osmium-grade heavy sarcasm]
Huh? Examples? How?
Then they're bisexual, not homosexual.
