Agree with you in general, but I think a lot if people here are not really informed what differences there are materialistic ideologies.
Yes, Stalin bad.
But Guevara is not Stalin.
Marx is not che
Engels is not Marx
China is not communist.
Marxism is not materialism
Socialism is not communism
Also the amount of people bringing the "the 3 times people tried socialism were bad, so the whole ideology must be bad" argument are way to high IMHO.
How many times was capitalism tried? How many times it worked out? Is the USA a "functioning" state with all the oppression, racism, greed, invading other countries out of monetarian interest and environment destruction?
While I agree with you, that oppression is bad, no matter what the oppressor calls himself, we should talk about policies without resorting to dogmas and generalising people in favor of fear the hegemonic class is propagating to stay in power.
