Criticism and hatred are two entirely different things.
I feel bad for Serpentza in particular because he basically went through this shit twice. The first was in South America, where you have a bunch of rabid baboon people who are all "END APARTHEID!" while they hurtle towards pulling a Zimbabwe 2.0, seizing all power and infrastructure from the whites so they can let it all rot into dilapidation. He reads the winds and gets out, moves to China, becomes an English teacher. He learns the language, he learns the culture, he marries a Chinese woman, he has a Chinese son. He has no meaningful allegiance to a foreign body, because his homeland has become a joke state. He describes a moment where he had a singular disagreement with a business owner, couldn't recall what it was over, and the man basically started trying to form an angry mob against him on the spot, yelling, "this man says he hates all Chinese."
He basically had to get out of dodge with his wife because the government was getting too creepy with keeping tabs on him and his videos. It was not because he hated China or Chinese culture. He expresses love for both often.
