Are you going to argue that there is more racism in a Texas company than a California company? You are really going to have to prove that.
Have you ever actually lived in a city such as Houston? One of the most diverse cities in the country.
Look how segregated Silicon Valley is. Cupertino and Saratoga Schools are —- about 80% Asian and 2% black. How is that possible given that racism is a “completely unacceptable” idea in California? Those schools are reflecting the employment of the region. Since those are expensive areas, only people with wel paying tech jobs can live there and yet the diversity is pretty much the opposite of the US as a whole.
Perhaps Silicon Valley needs to be called out — far more than those “racists in the south.”
