Pretty easy to be negative on China when all the news come out of there are: dictatorship, imprisonment millions in concentration camps and brainwashes them, builds artificial islands and claim ownership of seas not even close to their land, blatantly disregards WTO rules and closes off its market to others, hacks and steals other countries and their companies IP, threatens to attack a democratic Taiwan every day, censorship of their citizens, threatening censorship of other countries about China or its concentration camps, depletes fishing supplies in other countries, floods the ocean with plastics, props up dictatorships in other countries, etc etc etc.
I can't fathom how you could post this or the other comments you dropped in this thread. They're obviously bannable offenses, but since you've mostly posted fine comments to HN otherwise, I'm going to assume you went on tilt for some reason and not ban you. Please don't do it again though.
