I am making it clear that Facebook isn't only "failing to act" against Holocaust-Denial groups. Thus the title is overstating the case. If one is looking to be offended, I can assure you that I will find something that will offend you.

Facebook isn't even that bad - all these groups are marginal gatherings of insane people. On the other hand, one of the larger groups on Mixi is dedicated to denying foreign-born Japanese residents the right to vote (even if they pay taxes and what-have-you). It is mainstream - that's a lot more scary than some dead-enders on facebook.
