Of course the man should absolutely not have killed her, goes without saying.
But this shows the snapping point some people are at. He is indeed personally responsible for his action. But that does not nullify the tyranny of mazk enforcement, lockdowns and the thousands of deaths and injuries caused by covid and the vax by the various governments and elites.
This has caused countless losses of income, livelihoods, businesses, suicides, and horrible disruptions and those already on edge, with anger issues etc can and have been pushed over their snapping point. That is the larger point here.
That’s the essence of my point, only you said it better than I did. He’s 30, he may have lost his job due to covid, may have had a wife and kids or a girlfriend and lost them after losing his job. He may be hoping he gets covid and dies too and that’s why he’s not wearing a mask but, at the moment, he just wants to buy something to eat and now this SJW is piling on. We can’t know what’s going on in people’s lives or heads, but these are not the times to challenge a stranger, and I reiterate that people should maintain maximum politeness in public, for their own safety and the amelioration of society. That’s not a bad policy even in the best of times.
