Governments of communist countries have killed millions, not communism itself. Communism is a political theory designed to try and support the common good and break a cycle of oppression and revolt. Hasn't worked in practice, probably won't, but it's certainly not a hate doctrine like Nazism.

Glorification of the USSR would be more complicated, and could be perceived as endorsing violence.

"Individuals of Nazi ideologies have killed millions, not naziism itself."

If we're banning one -ism because it's considered violent/hateful, we need to ban all of the -isms that are more hateful/violent.

The primary element of Nazism is violent racism. This is somewhat unique among political ideologies and makes these comparisons poor. If you ask a communist to describe their utopia, it almost certainly doesn't include millions of people being executed by the state. But ask a Nazi and it will.

Have you met any tankies.

They do advocate for millions of class enemies to be killed.

Personally I feel, and I know many people disagree, that parallels between today and '30s are overrated.

While history can rhythm, the modern left and right have mythologized that period to the point it is unrecognizable.

People don't actually read books on WWII.

Just because they don't describe it doesn't mean it doesn't happen.

Communist governments have killed more than Nazi governments. Banning one without the other is hypocritical.

Perhaps Reddit is okay with being hypocritical, just as long as they own up to it.
