You realize there has been three China since 1900? Qing dynasty -> Republic of china -> Current China. Also wtf are you even saying? You know the first thing that comes out from “Chinese atrocities from 1900” in google is the boxer’s rebellion? A push back from the people against the invading foreign powers that were starving China? This is like blaming Hamas/Hezbollah for pushing back against Israel, which i imagine you also disapprove of. Truth is that for most of the 19/20th century, China has been a recipient of atrocities by foreign invaders not a perpetrator, you should be aware of this if you’re so aware about the scale of China.
