Many blacks resent the Asians who do business in their neighborhoods. This illustrates a couple of reasons why. The Asians don’t trust their customers and prefer to do business with them through a window. They also aren’t inclined to honor the blacks’ right to bellow at people and get in their faces and actually resist. And on top of that, notice that none of the employees are black.
The children of the store owners are likely at home studying hard. They will go to school and learn a profession. They will not keep shops in black neighborhoods. That will be up to the next wave of immigrants from cultures/nations with entrepreneurial traditions.
They also resent Jewish people. Just last year the number of anti-Jewish attacks in retail stores such as food markets by persons of color targeting them went way up. Even the lamestream news media had to notice it for a brief time. Then censored it again.
All the Walgreen and CVS stores are leaving San Francisco so the only ones open will be convenience stores where you have to conduct business through bulletproof window.
