Sorry i don't completely agree with you. "Is it amazing that many of us in the West thought he got trampled by the tank, when he never did?" True, we don't know what happen to him. Another proof that china is just trying to erase this story :

"While at the same time our govts mass murder innocent kids in gaza and we try to ignore it?" Sorry i don't agree. "our govts" are trying to do something, and people too, but the one in charge is the butcher Netanyahu. We can't send an atomic bomb on him so we just do our best. But certainly not stay there eating pop corns. Another proof :

"China? I'm much more worried about America and Australia manipulating history." Really ? Take a look :

List of genocides - Wikipedia

Persecution of Uyghurs in China - Wikipedia

Annexation of Tibet by China - Wikipedia

Taiwan, China - Wikipedia

I agree America and Australia can manipulate history too, of course, but not at the same level as dictatorship can. Thank you for this opinion share.
