US at least gives concerned citizens a framework in which to enact change, with China there is no such framework. Free speech on the internet in China is non-existent. You will not get censored in the US (or internationally) due to anti-American rhetoric. Sure there are currently flaws, but I am confident we can improve as humans in figuring out more meaningful ways to share our thoughts online.
I said this in another comment, but I will repeat it here; better the demon you know than the demon you don’t. With the preliminary data we have with the treatment of Chinese nationals living abroad, particularly in HK and Taiwan, and the continued rhetoric implying jurisdiction over all Chinese nationals worldwide, I don’t care to see what that world looks like.
