"It's already been decided, we had a world war about it"
Dobson clearly doesn't understand that most of the actual Nazis that were alive during WW II, if any are left alive, are now well into their 90s, and that "Nazis" of today DID NOT LIVE THROUGH WW II. It makes a difference when a person doesn't live through the era of the decisive battle.
He also doesn't understand that this isn't about DECIDING who is right.
It's about trying to convince people who are wrong, that they're wrong. It's also about trying to steer people out of that direction that may not be there yet but if something isn't done, they will drift that way. (Dr. Jordan Peterson said he's been able to steer a number of disaffected young men AWAY from the Alt-Right.) Nor does he understand that by trying to "suppress" an idea by "shutting it down" only drives the opinion underground, where it can fester and grow despite Dobson's naïve idea that by silencing and suppressing it that it will somehow go away. Sunlight is the best disinfectant to a poisonous ideology. Obviously, people who continue to hold Nazi opinions (or anything remotely like it) haven't been convinced that they're wrong, yet. True, there will be some that can't be convinced. But what is Dobson proposing to do with such people? Firing squad? Concentration camps? Forcing them into homelessness so they can starve on the street once exposed? How will starving them and firing/dispossessing them cause them to realize they're wrong? I'm genuinely curious.
After all, isn't oppression the way people start to think they're
right rather than wrong? Their reasoning is, if it were so obvious that Nazism is wrong, why would the powers-that-be be working so hard to make sure nobody hears it? It fosters a victim/oppressed mentality similar to that common among the IngSocJus crowd, including the whole martyrdom complex, and that's NOT a good thing.
Any

wanna point out to Dobson that at one point, it was Civil Rights that was considered to be "wrong", already decided, and thus not on an equal footing with Segregation?
