The redditor "Tienanmen Square massacre" narrative is flat earther levels of crank shit and needs to be recognized as such.
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.
"He maybe wasn't ran over by a tank, but lets not discount the possibility that we actually universe shifted, and we're originally from a timeline where I was always correct. look up the Mandela effect."
