So I think OP is trying to insinuate POTUS' behavior inspires a general lack of decorum, a la trickle-down dickonomics. Which is a sentiment I can't in good faith disagree with entirely, but it seems like a stretch in this case.
When I'm not being conscious, I tend to be pretty negative or sarcastic and even trend towards passive aggressive. I've found it to be rather damaging for a number of reasons.
I find when I choose kindness, not only is it more effective at accomplishing my goals, but I am happier and I set a better example for those around me. I find the kinder I respond ESPECIALLY in situations where it feels undeserved, the more positive impact it has.
To put it in more cliche terms, I want the world to be a kinder place, and I am trying to be the change I seek.
So yeah, personally I think it's a bad thing. Ban em, sure. But why take it any further? And FWIW, I'm sure the "threat" of ridicule is more tongue in cheek than anything, I was just trying to elaborate on what I suspected the other commenter was intimating.
Edit: that person (or bot) has almost exclusively posted on this website about the current US president. I think it's a waste engaging and I already regret my comment here
