So, should gays be allowed to get married? Sounds like a pretty straightforward "yes" or "no" answer. You either think it's okay or you don't. But the issue of a constitutional amendment banning gay marriage throws a kink in it. Less than 30 times has our Constitution been amended - in more than 200 years. And this debate has raised the question of whether the federal government should even be involved in who can, or can't, get married.
