Have a watch of this short history of the proud boys and tell me if an organisation like the proud boys merits being banned anywhere: https://www.youtube.com/watch?v=vsNlteJQunc
It's also very curious how organisations like BLM or antifa never make it onto these lists of boogeymen that need to be censored, even though they've said and done plenty of despicable (even criminal) things. Ever wonder why? It's for the same reason that not a single piece of fake news about Trump has ever been censored, even though real news about Biden is being censored and called fake news (remember the Hunter Biden laptop?). It's because censorship only serves to consolidate and protect the power of the authoritarians who implement it. That is dangerous no matter which side does it.
