There's so much comedy being made and so much of it is funny, from stand up comedy specials to comedians doing podcasts to late night TV shows like Colbert, Kimmel, Meyers, the Daily Show and so on. Most of these are leftists and they are hilarious.
I don't watch movies very often so I don't know if there are funny movies, but I imagine that there are. There are also hilarious comedy TV shows, like It's Always Sunny in Philadelphia, which is so weird and silly it avoids politics completely.
"Wokeness" only killed comedy for those who think the only funny jokes are at the expense of women, immigrants, minorities, and vulnerable people generally. Those jokes are awful and were never funny.
As for Jerry Seinfeld, I don't think he's a nice or likeable person, but I think he's generally quite funny. But this was a stupid comment for him to make.
