Oh, I agree! I don’t think OP is an intentionally bad actor, at all really. I would, however, bet with absolute confidence that they have never actually engaged with Marxism or Anarchism, which is why it would be fantastic if they agreed to read leftist theory. It’s just frustrating to see nothing but left punching from OP and judgements on who is left and who is right without engaging with leftist theory themselves.
Your second paragraph absolutely resonates. I myself used to be a “centrist,” then a liberal once I actually grew up a little bit, then became a leftist during my college years and have been reading theory and trying to better my understanding ever since. To be called a fascist when I know for absolute fact that I stand to the left of OP just frustrates me.
That all being said, I don’t believe OP is bad-faith, just not familiar with leftism and haven’t really done any reading. I’d be thrilled if they agreed to read Marx, but they have probably mentally written me off.
