It's silly to try and defend the position that being gay is "normal" because as the first post stated it's an evolutionary dead end.It probably is a genetic defect of some sort.Since being born gay is not something a person can help there also is no use in trying to change a persons sexual orientation. If you're gay or straight you didn't have a choice in the matter in your mothers womb.People need to get over the fact that at times natural selection produces mistakes in biology.
