The 800 lb gorilla in the room in 2021 that few want to mention (and the media chooses to ignore completely) is that a not insignificant number of black people think they have license to bully Asians... and a not insignificant number of Asian aren’t taking this crap.
A few weeks ago, I personally witnessed an older black man in San Francisco viciously insulting and berating an Asian woman working at a supermarket.
Any Asian males from Singapore, Taiwan or South Korea spent at least two years in the military because each nation has Universal Military Induction (UMI). They generally know how to do the hand-to-hand thing pretty well.
I am just a bit north on the 101. It is bad here, I cant imagine living in SF
