Not quite totalitarianism: the dictatorship of the proletariat isn't so much totalitarianism but the proletariat forcibly diminishing the bourgeoisie.
This highlights the mistake in your earlier post: the terminal point of all communism is a society without a government, which is why critiques of central planning made by capitalism apologists are so laughable. The difference between it and anarchism is the presence/lack of a transition art "dictatorship of the proletariat" stage. The disagreement over this between Marx and Bakunin is what tore apart the First International
The only way a person can continue to push this stuff so obnoxiously and aggressively is if he is actively fact-resistant - aggressively share an uninformed opinion and then deliberately avoid understanding anything in what you read that directly contradicts that opinion
oh right to a world with an untouchable police union and cops doing whatever the fuck they want to people with literally no consequences
also it's funny how when people throw a fit about cops killing innocent people and protest the cops tend to get prosecuted or at least have charges filed against them (usually months after they've done something wrong)
