One thing I think people do a lot of is conflating the concept of Communism with the real-life examples of governments that are described as such. I don’t actually know that Socialism or Communism as an idea is the problem, it’s that once the reality of governing and human nature is factored in it’s untenable. Capitalism has the same pitfalls. In a vacuum neither is necessarily bad, but the nature of Communism and Socialism lead more directly to an overly powerful State. So I don’t really begrudge the college kids who embrace the ideologies because it’s ideologically fine. It’s when they can’t recognize the issues in practicality that I think they should be roundly mocked.
