@Laura2592 In the US, at least, I see that the populace was given permission to act on the antisocial behavior that many kept more or less under wraps before. Punching a store clerk in the face for insisting that one wear a mask in the store or leave, screaming insults at minorities, attacking one's neighbors for the political signs in their yard, has become shockingly commonplace.
So it isn't surprising to me that people would have no filters for expressing whatever they wish to without considering whether it would be rude or offensive.
