Nobody ever directly engages the devs on the articles that created this whole affair. They simply accuse them of some vague "human rights denial" "genocide-supporters" "tankie" without any real substance. Go ahead and search out the articles. I read through some of them.
Yes, they are leftist essays. The devs didn't write them, they just compiled them together. I skimmed through a couple and read the titles of the rest. Some of them deal with topics such as Maoist China and the number of deaths from the Cultural Revolution. The article puts together an argument, with cited sources, that the common death figures are overblown.
Maybe the author is wrong, I don't know. I'm not an expert in this field nor do I have the energy to do as much research as I'd need to feel comfortable leaning one way or the other. But from reading the article, at no point does the author condone genocide.
Is this what we've come to? Someone can't post an article challenging one small piece of the narrative without all of a sudden being totally disavowed? I think it's absurd. Wrong or right, people should be allowed to discuss and share reasoned analysis.
