This shit has seriously gone on too long. People who continue to cling to the "10,000 dead crushed by tanks hosed i to the gutter" bs are cranks. It's jews control the banks, chemtrails, the earth is flat, the moon isn't real level of crank shit and unless you're feeling very indulgent and someone is asking in good faith it can be dismissed as equally serious to that kind of crank shit.
Thank you! Just to add even more sources regarding the reality of the 6-4 incident, here is a carrd with a whole slew of good links with descriptions. Some are redundant with the links you posted, but there are a lot of others, including things like the full "Tank Man" video and a section with "Mentions in State-Owned Media In China [refuting the "censor" narrative]." I believe our comrade @robinnn@hexbear.net put it together (along with other ones on Xinjiang, DPRK, and the Holodomor).
That Xinjiang one is outdated and has a few mistakes and the Holodomor one uses a video that is now private and was incomplete to begin with.
