I posted a link to that interview yesterday, and that was one of the surprising comments. His view was that although he's Jewish and finds it abhorrent, holocaust denial should still be acceptable on Facebook because "people should be allowed to be wrong on the internet".

Actually I don't think that flag will fly in the EU - despite recent political trends - and he is likely to encounter more trouble if he continues with this policy.

This is revealing of a weakness of Facebook which could be its eventual undoing. Facebook presently doesn't know how to do community based moderation. Zuckerberg thinks he can do it by hiring a few more censors and relying upon AI, but I don't think that's going to work out.
