Funny thing is it will work better than masks, which only have an effectiveness of reducing spread by 1.32% (CDC). While blacks has a much higher prevalence of WuFlu than whites, exceeding that percent. Avoiding blacks works better than a mask. What's great is you could almost get liberals on board because in their mythos, covid is the only thing that matters, and also in their mythos, blacks would benefit in regards to covid with less social interaction, so you would be helping blacks. Which, also in their mythos, is a good thing to do.
