I'm not surprised by this. I wouldn't even be surprised if that black man was in last year's BLM protests. He is a typical product of the 'divide and conquer' American strategy.The thing is the racist is a black guy! I mean come on. Of all people, he must have suffered racism sometime in his life living in white dominated U.S. and so know who it felt to be on the receiving end of a racist rant. Yet, he feels strongly enough to deliberately stopped whatever and where ever his going to make racist remarks at innocent Asians going about their business. Gee.
The Black folks in the US have been taught that Asians are the 'model minority'. Since many Blacks suffered from economic hardships due to, but not necessarily to systemic racism, some jealousy is formed. Hell, they even dislike the Latinos for the same reason. Then the US leaders started to stigmatise the Chinese. "China stole your job". "China Virus". "CCP agents in America". Then these already angry Blacks have an obvious enemy to hate who is not their White oppressors.
This 'divide and conquer' strategy have created the worse kinds of Sinophobia racism amongst non-Whites. It has even created anti-Chinese racists among ethnic Chinese themselves in HK, Taiwan, and around the world. So it does not surprise me at all that Blacks in America would join in on the China-hate.
