Mine is a safer proposition for the oppressed, for the minorities, for those not algined with the politics of the elites.
The whole argument about Nazi resurgence really falls flat when you realize that people get called Nazis for spousing wrongthink politics.
Your whole proposition is "the dangers of Nazism are too great". That's the same tactic I mentioned of "the dangers of communism" are too great.
If you want, ignore dictatorships. The slippery slope in non dictatorships is extremely damaging.
You're not gonna limit your censorship either, as you suggest in your last line. You're going to use it against your political foes to continue in or seize power.
Your motte and bailey tactics to get people to accept "some censorship for their own good" and then censor their speech that goes against your politics by calling it "Nazism" is a way bigger threat than the actual chance of "Nazi ideology". There was a time the ACLU safeguarded the right to say the most abhorrent of views the same you make sure due process is served even with the alleged most abhorrent criminals.
It benefits everyone.
Despite very strict censorship laws related to nazi propaganda, nazi symbolism, and Holocaust denial, Germany ranks much higher than the United States in terms of press freedom and has ranked higher for many years. There is no serious argument that (modern, reunified) Germany is not a free society where people are free to criticize the government. Yes, there are limits to the ideas that are allowed to be publicly promoted or debated, because the same concerns about a resurgence of nazism remain relevant today (it has actually become worse in recent years).
The abuse of censorship laws on the part of dictatorships is not an argument against all censorship, any more than the abuse of the courts by dictatorships is an argument against the rule of law. Expansive censorship is a problem that works against the interests of a free society, but limited censorship is sometimes necessary to promote the interests of a free society.
