u/WeilaiHope - originally from r/GenZhou
r/China is a racist subreddit with the purpose of hating and slandering China, which is reddits general position towards China. Most people on that sub have never been to China and just enjoy having a free pass to be racist, or are racist foreigners living in China who hate the country and people so much that they continue to live there and reap its benefits. Numerous even more racist china subs have been banned, creepy sexpat subs about China too, but they all gather around r/China.
r/Sino is the actual China subreddit.
