This argument boils down to “You want the government to do a good thing, but bad people can abuse the government to do the opposite.” Sure, that happens sometimes.
But following your logic, I guess all laws shouldn’t exist then. After all, if we give the government the ability to do anything against any citizen, they might use it in a bad way! This argument is fundamentally unworkable, because it doesn’t just apply to enforcing rules regarding speech, it applies to all rules.
Yes, I believe the government should enforce the standards I believe are correct. No, I do not believe that simply by enforcing such standards the power is magically granted for them to use it incorrectly, in a way that they wouldn’t be capable of had my preferred regulation not been implemented. Whether Nazis are or aren’t allowed speech won’t stop a bad government from simply censoring acceptable speech, if the government is acting in bad faith. They will do so regardless of if anti-Nazi speech regulations were in place prior.
Should we never attempt to implement any positive policy if it grants power that could theoretically be abused?
Nazism, however, can be more objectively defined than single-word terms, as you’ve used here.
For instance, if someone says the words “Heil Hitler” while raising their hands in a traditional Nazi salute, there isn’t exactly room for a fascist to go “weeeeelllll but you saying ‘black lives matter’ with your fist up is the same thing, actually,” if the law explicitly states that saying the exact words “Heil Hitler” while raising your hand in that salute is the specific thing required to get you imprisoned. Laws can be more objectively defined than “pedophiles,” “supporting enemy invaders,” or “Nazis.”
Nazis simply ignore the law. Trump is quite literally doing it right now, He’s passing executive orders he doesn’t actually have the legal capacity to enforce, which is then leading to things like congresspeople being prevented from entering buildings they have a right to enter, or databases being given to people without legally required security credentials. They don’t care what the law was, they care what it will be once they’re done screwing with it.
Whether or not you pass a law prohibiting explicit behaviors that are categorically harmful to society will not change whether or not they are then capable of manipulating the laws to do what they wanted to do to you regardless.
It will, however, heavily reduce the chances of them coming into power, and having the ability to misuse any laws or power they may have in the first place
And yes, it obviously does. You stated that we should not censor Nazis because Nazis in power later on could use that law to suppress others. The same logic applies to any other regulation or prohibition. We shouldn’t pass gun control legislation because it’s possible someone uses it to take the good people’s guns away. We shouldn’t imprison people for rape because someone could redefine what rape means to mean non-married people having sex. We shouldn’t jail pedophiles because they could redefine trans people as pedophiles simply for existing.
It’s the same logic all the way down. There is nothing different when it comes to imprisonment for Nazi-aligned speech/actions, or other dangerous speech/actions. All of them can be prohibited to an extent, even though there’s a possibility that the power dynamic could then be reversed later on by the same group of people being prohibited.
Look, I’m not going to keep going on this because I think it’s clear neither of us are changing our stances. Send a reply if you want, I’ll gladly read it, and give it some thought, but I’m done trying to continue a conversation if you think we shouldn’t try to stop Nazis because Nazis could possibly get in power and stop us instead. That applies to any regulation against any group that could possibly come into power, and I would encourage you to look back at the examples I provided, stop, and think about just how different the logic really is to the idea of censoring Nazis, because I think you’ll find it is, in fact, not different at all.
