this "debate" has become a circle jerk. There's no possible way that homosexuals should be compared to child molesters.
Incest and homosexuality also don't compare because offspring cannot result from a homosexual pair. Children resulting from unions between father and daughter, mother and son, brother and sister, aside from being utterly revolting also present harm to society because of genetic disorders.
It would be nice if the same arguments weren't being regurgitated over and over.
By all means, please explain how gay marriage will harm society. Meanwhile, people can keep their misguided religious sentiments to themselves. Religion and government do not mix.
