The “June 4th incident” was in 1989, not 1984, and neither Hexbear nor China says it never happened. Hexbear’s stance, and most Marxists in general, on Tian’anmen is that hundreds of protestors and PLA officers were killed in Beijing that day as the PLA advanced towards the square, but that the square itself was evacuated peacefully, which matches leaked US cables and the CPC’s official stance on what it calls the “June 4th incident”. This is a rejection of the commonly reported story of 10,000 people being killed on the square itself, which originated from a British diplomat’s cable. Said diplomat was later confirmed to have evacuated well before.

I reiterate, Hexbear’s stance isn’t that the massacre didn’t happen, but that Western nations intentionally sensationalize the quantity of deaths and the character of the events. This is also why Western Nations don’t frequently report on the South Korean Gwang-Ju massacre that occured around the same era, where the South Korean millitary murdered thousands of High School and College students protesting against Chun Do-Hwan’s dictatorship. All of what I said is backed up by the Wikipedia page for Tian’anmen Square Protests and Massacre, such as Alan Donald revising his estimate from 10,000 to the low thousands yet BBC continuing to report the 10,000 figure:

In a disputed cable sent in the aftermath of the events at Tiananmen, British Ambassador Alan Donald initially claimed, based on information from a “good friend” in the State Council of China, that a minimum of 10,000 civilians died,[237] claims which were repeated in a speech by Australian Prime Minister Bob Hawke,[238] but which is an estimated number much higher than other sources provided.[239][240] After the declassification, former student protest leader Feng Congde pointed out that Donald later revised his estimate to 2,700–3,400 deaths, a number closer to, but still much higher than, other estimates.[241]

You’re also just wrong about what fascism is and what AES states were structured as, so I recommend Blackshirts and Reds.
