I don't particularly buy into the "punching down" business anyway. If, say, male comedians want to make jokes about, say, women, I think they should go right ahead. If they are true and funny then people will respond to them. If people don't like what they say, they shouldn't watch, and if no one likes it, the comedians will not get Netflix specials.
As for Gervais, I thought some of it was almost a little too mundane to be super funny to me. But I think it would have been more effective for some other people.
One thing it put me in mind of, I remember years ago people saying that comedians on the left could be funny because they could be anti-authoritarian, whereas comedians on the right tended not to be in the same way. While I wouldn't exactly say people like Gervais or Chapell are on the right, there is a sense where that has really flipped. The targets of progressive humour are so weakly presented that they tend not to be funny. It's like Trevor Noah making fun of something Trump said by just repeating it (and not always accurately, even, which means it's not funny at all.) You see the same thing around critisism of older comedy by progressives, many don't understand where it was looking to undermine certain viewpoints, or they are so uptight about langugage that you can't even present certain ideas.
