Most jokes 'about men' are really jokes about women, @TheMoonismadeofcheese. The majority of the remainder are about men wanting to shag women or not wanting to be married to women.
See, that's what the punching down comment means: able-bodied white men being the ruling class, they have zillions of jokes lampooning women, brown people and people with disabilities. A lot of those are so breathtakingly cruel, they barely count as jokes unless they can be construed as poking fun at the arrogance of a system that produces such jokes.
With jokes by women about men, by brown people about white people, or by disabled people about the able-bodied, there's a subtext of rebellion. That's what horrifies the complainers on this thread. Interestingly, few men would be offended by these jokes because a confident person can afford to laugh at him/herself.
... and trying to explain humour to the humourless is a notoriously thankless effort! Brighter people than me have been trying since Ancient Greece, always unsuccessfully.
People who have no sense of humour ... have a serious problem.
No, I'm not explaining that one 😉But then again ...
If you lose one of your senses, your other senses get enhanced. This is why people with no sense of humour have a heightened sense of self importance.
