I'll start off by saying, I am going to quote-reply a bunch of things from your comment. Don't take it like I'm trying to be a debate bro and own you online. I actually think your comment is quite constructive.
Something like 6 million people died in the Holocaust and there is plenty of evidence to show that.
Six million Jews. This figure excludes the Roma, LGBT, Neurodivergant, Communists, Anarchists, partisans, and prisoners of war. The total figure lands somewhere around 10-11 million, at least according to the US Holocaust Museum.
But consider a world where you canno make an academic or scientific inquiry into a topic because “the issue has been resolved”. What kind of world is that? He was defending a researcher who did an analysis into the Holocaust and came up with significantly different figures.
In abstract, I completely agree with this, but we live in a world where the reactionaries have more money than God to churn out this sort of self-serving analysis, and debate subjects which ought to be settled. We live in a world where government and think tank employees get paid to spend eight hours a day revising history on Wikipedia while volunteers and academics have to worry about keeping a roof over their heads. We live in a world where we're still debating the right to abortion in the year 2023.
As such, I am much more interested learning the lessons of the triumphs and shortcomings of the masses of people who fought against this evil than I am about debating whether it was really even evil to begin with.
To repeat myself, I have never heard about this take from Chomsky, and I'd be interested to learn about it in detail. I assume it is actually benign because there are a significant amount of people who criticize Chomsky from the left and I have never heard them mention this.
So we bring it back to the Lemmy devs. The article I read (I didn’t read them all) was an analysis of the death toll of the Mao period and claims the figures were inflated. Does someone posting a link to this or otherwise sharing it make them a “genocide denier” and a “CCP tankie”?
In general, I think the Western audience knows absolutely nothing about this history. This is not limited to the layman Redditor, but large swaths of academia and the fourth estate as well. It would be fascinating to see what answers you'd get if you asked a random Washington Post or Wall Street Journal reporter to explain what happened in the Great Leap Forward or the Cultural Revolution with no notes. This is the standard I choose to hold the developers against. I am pretty sure Dessalines has the history pinned down much more accurately than the average American propagandist.

In general, I agree. The parameters of discussion on the big social networks are very heavily controlled. The largest communities on Reddit, like r/Politics, r/WorldNews etc. are extremely single-minded. Some places like r/AskHistorians tend to be a bit better.
