There is no evidence that I am aware showing that being offended by homosexuality is genetic. If 95% of the people are bigots all the more reason to change.
Bigotry is an evil and it is the moral duty of every person to eliminate it. This is best done by freeing children from the delusions of the past. But bigots crave company and the company of their children. Bigotry runs very very deep. It is self hate that masks itself as hate for the other. But while there may be benefits from a social stigma against intolerance, bigotry can't be defeated by hate. That is why it is important to remember that the bigot has a disease and is not responsible for it. He can see his bigotry and overcome it best if he is loved, because it is only love that heals self hate. This urge to ban Zendari is one that I don't understand. It's a rare bigot that stands forth and tells you he is proud to be one. The task at hand is to heal, not ban. Zendari has an irrational belief that Gay is evil, but he cannot prove that case without going to an old bigoted text like the Bible. His case is as absurd as the Hindu case against the Untouchable. It is nothing but irrational hate and fear and a form of mental illness. When did we start hating the sick? Hate the evil it does if you have to hate. Hate that Gays die dragged behind the cars of the sickest bigots. It is the same disease evenly more openly expressed. Most good people are ashamed of themselves when they see what their bigotry does to the victims we manufacture in this world. It is only in certainty that men kill. And the thing about bigotry is it's certain. George Wallace later in life asked forgiveness of the girl become woman he tried to keep out of a white school.
Humanity will awake from its Millennia sleep in bigotry and superstition or will kill itself over lies.
