I think that as long as in general folk do the right thing, if a few folk “unfairly” do the wrong thing because of extenuating circumstances like having cancer (or a family member having that or something else serious)… well, that’s ok. Calling for universal absolute behaviour from everyone is unkind, and, statistically not necessary for the outcomes you want. Basically; it’s easy to say “call them out!” when it’s not you and youre not taking any risks. Pretty nice and comfortable to sit in your armchair and say that… I think there are a lot of people here to want someone else to do it, but aren’t willing to do it themselves.
