Its about having a just society Mehmet. Surely having children isn't the only way a married couple can help it. And your argument fails because there are alot of hetero couples that choose NOT to have children, what you're gonna do? Force them to do that? As an hetero married guy, I don't think the fact that gays can marriage take any value away from my marriage, nor have any detrimental effects on me. But I do feel better knowing that 2 people that love eachother can have the same rights and protection me and my wife have.
I sincerely hope that when you have children, they don't turn out to be gay, not because of you, but because of my concern about that hyphotetical child having to deal with his own father's bigotry, and the whole suffering that would bring.
