People like Raedwulf and Giok don't do their homework about these sorts of things, because they fear that learning the truth will challenge their bigoted beliefs. So they "don't care" or claim they were being ironic, or were just kidding, or what have you. That way, they feel perfectly justified in their spewing hate instead of learning the truth, and challenging themselves to grow into compassionate, empathetic human beings. If they opened that can of worms, they'd be forced to admit their prejudices, you see. And that would rock their world too much.

That's how the bigotry game works. You MUST maintain your ignorance of other people.
