That's a very reductive and simplistic approach on things that fails to acknowledge both what has been done and the precedents it allows to happen.
And please... "Trump supporters upset by jokes made by comedians"? That's delusion to think these comedians aren't actually serious when they call anything under the sun slightly right of their own political position a "nazi" or a "fascist" that "should be killed", "eliminated", "removed", etc... under the guise of quirky puns and laughs-in-a-can. In addition to being fundamentally dishonest regarding the entire context in which these "jokes" and "childish insults" are set.
These are not jokes, they are calls for violent activism. Which, incidentally, led to a number of politically motivated criminal acts, some resulting with deaths, and several attempts on political figures (including SC Judges).
So, one might and should ask oneself "are these really childish jokes made by slop comedians"?
I'm sorry but calling for someone to get killed and then coming up with a "good" after the attempt has been made isn't about "respect", "living together", "being over-sensitive". Unless the underlying message is: well, respect, living togetherness and such will be achieve once the "over-sensitive" ones are removed.
You also have to ask yourself: what is an insult? Is the alleged insult an actual one, or is it factually correct?
For instance, Biden got called a demented geriatric pedo. Is that an insult or is it accurate?
For instance, the leader of the AfD got called a nazi and such. Is that an insult or is it accurate?
For instance, Mélanchon got called a populist antisemite. Is that an insult or is it accurate?
For instance, Trump got called mass-murdering spawn of the Devil literally worse than Mao, Stalin Pol Pot and Hitler. Is that an insult or is it accurate?
