I'm well aware of the fact that people buy into the Utopian idealist part of communism, everyone is equal, etc., but Karl Marx didn't really think too hard about how we get to communism, or at least he left stuff out or just plain didn't understand human nature.
And even worse, once they obtain power, those at the top never give it up and just turn communist societies into their own personal fiefdoms.
I still don't think people should be jailed for beliefs no matter how wrong they are. That is not who we are nor who we should be as a country.
There are people who exist who unironically believe that, although there are a few socialist types in the DNC. People in America think when AOC types mention it they're talking of the Red Army and
@JosephStalin and gulags and stuff. A bit extreme but I understand where they're coming from. Unfortunately, those types tend to force their way in though, no matter what ideology they claim.
