If someone is stupid enough to fall for the lackluster logic of Neo-Nazis then I see that as a problem with our public education, not with the moderation policy of a website. Sure, enforcing "correct" speech at all times could potentially lead to more harmony in society, but I would much, much rather invest in empowering people to think critically for themselves. Many are already able to resist the persuasiveness of propaganda, ads, conspiracy theories, and extremist groups that are all around us today. Teach this skill of resistance instead of trying to baby-proof society.
