You should stick around and have a look what it's like when communists argue among themselves. At the moment it seems that you have a preconceived notion of what Marxist discussion looks like. I assume that means you haven't met many Marxists, which is common except in communist countries.

There are many things we have already reached agreement on, such as that something like 99.9999% of westerners are completely clueless about China and communism.

They don't want to know. They don't know what historical or dialectical materialism is, if they've even heard of the terms. They don't care for political economy (even their own liberal version of it). Otherwise they would be willing to look past what they have been taught and objectively weigh and consider new evidence.

Notwithstanding that the evidence isn't new; it just never generally reached the western public. Be confident that your ruling class knows what really happens/ed. There are over 150 years of Marxist literature that you very likely have never encountered or understood as Marxist. We're not just making things up or coming to conclusions based on vibes or predetermined notions of who's right or wrong (morally or otherwise).

Marxism begins with the concrete analysis of concrete conditions. If you have some new concrete evidence for us, by all means share it and we will arrive at fresh conclusions. It better be rigorous evidence, though, or it will be dismissed.

It's up to you whether you want to learn but if all you do is call us drones for accepting conclusions reached after years of research and struggle sessions, you're going to be disappointed.
