I’ve been thinking about the OP’s question the last few days and here are a few of my thoughts.
Do people seem ruder: in my opinion, the short answer is yes. However, I believe I’m observing rudeness more often online/secondhand rather than actually witnessing it in person. The part that I have found disturbing is not necessarily the rudeness itself…there have always been people rude/inconsiderate people…but the disproportionate response in a given situation. Escalation feels like a real possibility and I feel it’s become a tactic to intimidate others into submission.
Do people seem more easily angered these days: again, the short answer is yes. Imo the more interesting consideration is why. To try and keep my thoughts succinct I attribute it in large part to the general sense of frustration due to 1. Lies and 2. Increasing/changing power disparities.
