I see what you're thinking, but it's wrong. First of all, gay marriage solves part of the world's overpopulation problem. Instead of birthing children, gay couples adopt kids without homes. As for the "mental damage," in most gay couples, one person takes up the motherly role, and the other, fatherly. The world evolved to prepare for homosexuality, so this fills in the cracks. Yes, it says homosexuality is wrong in the Bible, but of centuries the Bible has been modified by untrustworthy people with different opinions. Nobody actually knows what the original copy said. Besides, God and the Bible and Heaven and everything like have not actually been proven. They might not even exist.
