Let’s be realistic, in a world of nuclear deterrence world powers aren’t landing troops on each other’s shores. But I think you’re right about this not being a safe place if you’re not a well off, white man or woman. There is a danger of an invasion but it’s not from the Chinese, it’s from American right wing extremists. A populist right is on the rise and it’s far more powerful than any genuine movement on the left in the US. Trump is just the beginning.

Those who are in the US could just give up and move away, which is totally understandable, but don’t pretend that pressuring the head of capitalistic imperialism in the world directly has no effect. US citizens arguably have the most potential to change the direction of world events, but they’re also the most subdued and comatose of all populations. But those of us that aren’t in a capitalistic stupor could organize and push the country in a better direction, but we will definitely be punished for it.

If OP chooses to stay, it’s going to be a fight. Not against China but against the powers of domination and exploitation that already exist here.
