Holocaust denial is, on the root, pure antisemitism, which has been an evil element of every Western society since the beginning of the diaspora. The ideology behind it is pretty much equal to that part of nazi ideology (and I'm not one of those who is quick to run around calling everybody nazi these days).

As someone whose school system has provided them with some insight on how this all happened I see the US absolutist view on free speech when it is about outright lies like Holocaust denial as a bit dangerous. Preventing deluted individuals from spreading a life-threatening lie is not censorship. I see that the US view is coming from a very humanist view here, but tolerance needs to have limits set by basic human rights values, otherwise it will be destroyed by itself sooner or later.

The approach to "educate the deniers" is indicating to them and the listeners that you are taking them and their delusions seriously, and dissiminate them in the process. In the current debates about e.g. evolution you clearly see what happens in wider society if you talk to the 1% "skeptics".
