Reading your post in the WH forum, fair comment Peri, I know where you are coming from.
I should note once again,
#1 - Re: Voltaire, I don't beleive in censorship - in part so we can identify the bastards! - but believe in ostracizing these polluted views so they don't feed on themselves, and
#2 - You do change people's attitudes by making it clear that they are what they are, however, and to a certain degree that's why I'm having this argument. Rmsharpe - for example - may be a hardcore right winger, but I don't think it's fair to say he's a fascist or a nazi. But what else are we supposed to call someone who argues that Hitler's big fault was hypocrisy for not standing up for whites more consistently? There are only a limited number of words to use to describe this outlook and the person who holds them, and better the poor kids (which they probably are) hear it now than later.
I have encountered a few personal examples where this sort of shock therapy has the opposite of the intended impact, as you say. But I have also encountered success stories - myself among them, given the childishly anti-immigrant and uninformed attitudes I had in my teens. It was only when it was clear to me that my ideas really were denounced and repulsive to normal, thinking people that I actually reconsidered them and became the relatively sane person I think I am today.
We recently had an intern who didn't get a job where I work because he was complaining about immigrants in the job interview. The guy is Jewish. When he asked our boss to explain why he - a party worker with impeccable grades - wasn't hired, we asked if he REALLY wanted to know. He said yes. He was told that his views came across as those of a racist, and racists don't get to work here. It had never occurred to him that a political office would see bashing visible minority immigrants as racist, because his assumption was that as a Jew, he couldn't possibly be considered a racist. He has since gone on to take steps to correct his behavior and thanked us for being so direct. If our people had just explained it as "your views on x are a little funny," he would never have thought twice about it.
