I have to say, I never thought I'd see this:
The compelling argument is on the side of homosexuals. That is where the compelling argument is. We’re Americans, we just want to be treated like everybody else. That’s a compelling argument, and to deny that you’ve got to have a very strong argument on the other side. And the other side hasn’t been able to do anything but thump the Bible.”
And you have to agree with O'Reilly's assessment of politician's evolution on gay marriage - it's mostly completely phony. Bill Clinton signed the Defense of Marriage Act because it was a popular thing to do at the time. It isn't now, so he's pro gay marriage.
