God help us when South Park is helping us find our moral compass...
I don't know that I agree with your sentiment. Irreverent comedians who have achieved significant success and not really accountable to anyone are perfectly positioned to "tell it like it is" and may be the best individuals to do so. I'm glad our society embraces and can cultivate such individuals especially in this time of cancel culture.
Exactly how many irreverent comedians who achieved significant success and are not really accountable to anyone, telling it like it is, have been cancelled by the cancel culture?
Cosby, TJ Miller, Louis CK, Jeffrey Tambor, James Franco, ...? A good list of people who did morally reprehensible things of varying degrees, from illegal to merely opening their employers to civil liability, and in my mind, they should be "cancelled." Maybe you can argue some of these, I don't think so.
Azis Ansari? I don't know how tranchant his "speaking truth to power" has ever been, but he did a Netflix special this year, and I would need pretty compelling evidence to believe that's your smoking gun. I predict he'll be just fine in a few more years.
Kevin Hart? Maybe. Again, not much of a politically-motivated comedian, but getting removed as Oscar (?) host was damaging. Nonetheless, it looks like he had 5 movies/specials in 2019 and has work scheduled for 2020. Besides the car crash, I think he'll be alright.
Dan Harmon (like James Gunn) was a political hit job and didn't go anywhere.
Am I missing anyone?
Outside of e.g. #metoo, some people didn't like Dave Chappelle's recent Netflix special. I'm not a fan of him "punching down" at trans people myself, but, I don't think it's anything he hasn't said before. Nonetheless it was trending in the top five for most of last month, I think he is, and will continue to be, doing fine.
I just don't see where people attribute all this power to "cancel culture." Chik-fil-A, Nike, ..., all doing just fine despite on-going boycotts from "cancel culture."
