While I do take a strong stance against flat-earthers, Holocaust deniers, etc.. I can sympathize with Zuckerberg here a little bit, because just banning Holocaust deniers is on a big slippery slope, that could lead to larger issues like "Do we ban religious speak against homosexuality due to instruction from an invisible man in the sky?" since we only deal in materialistic fact here and all controversial opinions are unwelcome. Where do we draw the line?
