Untouchability has a new definition. What Covid-19 has proved is that there are things that you would seriously avoid being in close contact with. You wouldn’t share drinking glasses with a Covid patient and nor would you consider coming to grips with one if you knew the person was positive. Of course, George Floyd had Covid when the cop kneeled on him neck down but that fact was not known --- presumably if it had been, he would still have been alive. Covid is a scarlet letter, the thing that results in those affected being shunned.
