As one of the “… or something else” political group, I agree with your remarks concerning the loss of respect for those with whom we disagree. This did not occur overnight, but it has been exacerbated in the past few years.
Leaders who use pejoratives to describe their opponents are a major part of the problem. Frankly, I think a “leader,” irrespective of political party, who uses childish terms to describe others, must have a limited vocabulary and is not a leader I would want to follow. Additionally, that characteristic is a poor example for others.
Recently, I was at a local business when another customer screamed, “I hate all the ____ and they all should be killed!”
An anomaly? No, I don’t think so. It is just another incident that was ignored by most of those present.
