Hello fellow sleep-deprived human! I am not proud of it, but for a brief moment I also thought that way.

What convinced me to reevaluate my views was discovering how brutal the US actions around the world actually are. I already agreed with basic idea of Communism and I thought that whatever Stalin was doing, it could not be much worse than what the US empire did and keeps doing everywhere, so I was curious what other arguments do Marxist-Leninists have.

Understanding that capitalism inevitably leads to imperialism and breeds fascism was another blow that convinced me that whatever happens in China cannot be worse than total society collapse and so on.

I had to peel layers of my prejudice, one at a time, starting from what I considered most believable to least believable. At some point I found myself agreeing with most of the ML talking points and I decided to let my guard down and start reading about provided sources with open mind.

I'm not sure that you can convince someone that there is no Uyghur genocide if they are emotionally invested in this narrative, because, like you pointed out, on emotional level for them it is like Holocaust denial or something similar. Besides, people tend to stick with others who already share their views and bias, so they reinforce their paranoia among each other (just like we reinforce our bias here).

Maybe changing material conditions will make people look for alternatives more seriously and reconsider their views. Maybe some need to actually feel some more effects of capitalism before they engage with a good faith discussion.

Sorry that I have nothing better for you, but I felt like rambling a little.
