Sure, there are extremes on both sides and those who want to silence any dissenting opinions. It's always easier to live in our individual bubbles and feel superior when you can label and dismiss anyone who might disagree with you. This applies whether you're doing it for religious/blasphemy reasons or social justice ones. Bill Maher's '90s show (that was canceled by backlash from the right) was called "Politically Incorrect" in response to the leftwing political correctness movement.
As to humor, for me the best stand-up humor comes from pointing out absurdities or inconsistencies in society and what we readily accept or take for granted. Observational humor. George Carlin was the master of this, and I'm sure for many reasons he'd be canceled on the left as he was hated on the right for continuously s##tting on religion.
More than ever politics has become almost religious or cult-like, with those not quoting chapter and verse or daring to question narratives being quickly shouted down, dog-piled on, canceled, etc. See Republicans who stood up to Trump in the last election for trying to steal it, and see it among those who question Biden (especially those who did so leading up to the election) from the center-left.
