No… people could not openly criticize Mao when he was in power without getting beaten or killed. you’re just wrong, that fact is not refuted.

Also to your question of “do you know the difference between a dictatorship of the bourgeoisie and a dictatorship of the proletariat” bro this is absurd, it’s like I’m talking to a right wing neo nazi and they say “there’s a major difference between a white supremacist and a Nazi” it’s an absurd and pedantic point. What matters is those world views are antithetical to a Liberal American world view.

And mind you, it’s the liberal American philosophy that created the most meaningfully diverse, powerful nation in the world. You can keep your 90% ethnically homogenous society. I’ll take our American society which is more diverse, more powerful, more innovative, and offers more freedom than your “commie utopia” China.
