The only white/non-black business I patronize on a regular is grocery store and gas.But you still shop at WalMart...
You still wear Ralph Lauren...
You still drive a Ford, Chevy, GMC, Dodge, Jeep, Chrysler or Lincoln...
You still get groceries at Whole Foods, BiLo, Lowes Foods...
If you truly boycotted white business your entire lifestyle would have to change
