You're lumping a lot of different ideologies together under one umbrella term, even though 1) they were wildly different in practice and implementation, and 2) most of them only paid the tiniest bit of lip service to what Marx envisioned, and 3) were actually just good old tyrannical dictatorships, falsely using the promise of communistic ideals to pacify the populace.

I've found it a very common tendency to lump everything free market capitalists don't like as "communism bad!" and "socialism bad!", which I guess stems from decades and decades of cultural indoctrination, fueled by the military industrial complex.

For instance, an anarcho-communist is very far from whatever haphazard centrally planned mess was in place in the USSR at any given time.
