You should try arguing something other than a strawman. As I have previously shown two polls (the poll had results from a previous one as well) show that white people wear masks at lower rates than minorities. So that alone blows your argument about minorities being disproportionately impacted by penalties for not wearing a mask out of the water. If they are wearing masks at greater rates than whites, then increasing the rates that whites wear masks while in indoor public areas actually benefits minorities.
Moreover, in virtually every city in the country right now, workers in direct contact with customers are required to wear masks and businesses can be fined for non-compliance. Which is the point, as demonstrated in previous links, workers that come into contact with customers are by and large already wearing masks, the problem is customers that are not in full compliance.
Which is where your whole intellectual dishonesty comes in. You are trying to argue that penalties for not wearing masks in indoor public areas would disproportionately hurt minority communities when in fact, from all the available evidence, we know that it would actually benefit those communities and reduce COVID infection rates in those communities. If someone is working as a cashier, it is to their benefit if everyone that they come in contact with during their work day has a mask on and is wearing it properly over their mouth and nose. Reducing penalties for non-mask compliance only increases the number of customers that cashier will come into contact that day that don't have a mask on properly, and thus doesn't help them, it hurts them.
