But, that's not a valid argument anymore since the vaccine is freely available and not so effective at stopping the spread. Anyway, people live in such different circumstances- some people may live in near isolation already, it's a jump to judgement to condemn someone without taking into account their situation. The largest spreaders are probably people with the most social connections, many of which are vaccinated- you could demonize people for all sorts of life choices that led to viral spread.
