I'm about done discussing this with you, as you already seem to have a reasonable amount of facts.

But your insistence that China fired upon peaceful protests based on "China’s authoritarian and notoriously opaque government cannot be trusted to tell the truth " is absolutely insane and not at all fact based. There's zero evidence to support that. The PLA must really be bad at massacres if they allowed that many of their vehicles and personnel to be killed by unarmed civilians.

Whataboutism or whataboutery (as in "what about…?") denotes in a pejorative sense a procedure in which a critical question or argument is not answered or discussed, but retorted with a critical counter-question which expresses a counter-accusation.

I have done nothing of the sort. I've addressed every topic. I'm inquiring further about why this one particular event is of such importance in showing how evil China is, while things like this are just one of those things. The fact that this keeps popping up every single year and actual American massacres are barely mentioned should indicate to you that the people running the propaganda machine really want you to hate China.

They've shown themselves very willing to twist the truth, but you still insist that the core claim is true, no matter what. The clear use of this as propaganda should lead you to question it.

But I doubt that any further conversation will be productive. You have the basic facts correct, which is better than most. Many people did die that night. Many of them soldiers. The fighting happened in many separate locations away from the square. Those are the facts. If you extrapolate a massacre out of that, there's no facts I can draw upon to argue with you, other than repeating that the burden of proof is on the accuser.
