All comedy makes fun of somebody. Good comedy makes fun of someone who deserves it, but conservatives can't identify who deserves it because it's themselves.

As has been noted elsewhere here, too little empathy or even camaraderie.
Too much punching down vs punching up.

And (largely because of that) it has been the opposite of clever. It has been pretty much all direct cheap shots.

It's for the same reason old men think the three stooges are funny.
It gets worse as you go back through history.
At the "Joust" of the Middle Ages they would sometimes tie a cat to a stick then stick him in a bonfire and the crowd would laugh. It was like going to the comedy club for them.
Some of us have developed enough empathy now to not find humor in cruelty, but certainly not all of us.
If we are to survive that empathy has to become synonymous with being human or we will kill ourselves through war or by ignorance and doing something like poisoning ourselves, like we almost did with Teflon and refrigerants that eat ozone.
We must also transcend being "physical" oriented creatures, not in a religious way, like all those ships and freight trains are about us getting physical materials from where they are found to where we are. It's why bosses have little tolerance for people not coming into the office. The pandemic proved we can work from home, saving time, resources, and stress. For me this was no problem, I'm ready for G666 @@ networking brain to brain, or spend all my time on computers.
Life is about knowledge and information, not possession and proximity.
Now convince someone that possesses a shit ton of stuff and has proximity to paying for the rule changes necessary to have even more proximity to their possessions.
This phase should last 350 to 500 years, I hope we survive, we haven't even figured out CO2 yet at a socially responsible level.

Because most conservatives these days have no sense of humor. The height of hilarity was apparently Trump mocking a disabled person. What they refer to as jokes is really just insulting people who aren't there to fight back.

Because it's stupid, about a 2nd grade level stupid.
