“how can you boycott a black owned business if you don’t know of any”
I let Amazon tell me. All things being equal, I avoid sellers that participate in identity based promotion. Also, when brick and mortar shopping, I avoid stores that try to exploit identity credentials.
Completely agree- there’s a shop here in town with a “Black Lives Matter” sign in the window. I will never step foot in it.
I also try not to spend $0.01 at Amazon
