Well other than growing around a large community of Han Chinese immigrants who all have different views on it sure. They are all generally aware of the racism issues in China particularly against black people. I'm assuming you have a much broader experience in China yourself and have seen otherwise outside of forums? If so I'd be more than happy to be wrong. But if first hand accounts from people who love China tell me that the country has a major issue with rampant racism, and have even told me that I wouldn't be a good fit for the country due to not being light skinned, I'm obviously taking that to heart.
It's possible to be critical of a country's issues without implying that I'm accusing the entire population of being racist ๐คทโโ๏ธ
Yeah I suppose you're right, I've only heard about this regarding Guangdong and the likes. That said the cost of living is still significantly less than most Western countries. I suppose I just meant that it's easier to adapt and avoid the social issues if you have money but that applies anywhere.
