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.
This is my go to for the power of propaganda but it only works in person. It's "Do you know what happened to the Tank Man at Tienanman Square?" People almost always answer that he was run over. The response is great because while we don't know exactly what happened to him we know one thing for certain; he was not run over. That's the one thing we can say for sure and its the one thing they believe happened through the power of propaganda.
