thing is though, that wouldn't effect the idiots who read the racist ones in the first place. just like religious fundamentalists, or indeed anyone with an ideology based worldview, anything that doesn't agree with them is dismissed immediately. There's no reason to consider it because it can't be true, it doesn't agree with me.
Also, don't be too put down by these. They might seem to be a lot of people, but really they're just a tiny minority. Their existence can concern and disgust you, but don't think they have power, because they don't.
edit: Mile beat me to my first point.
