I want to agree with you, but Bill Hicks. He was a terrible entertainer. Until he was well known enough that he started getting audiences who wanted to see Bill Hicks instead of audiences who weren't expecting him, he had a career because other comedians liked him, not because his audiences liked him.
I guess I could respond with a "Larry the Cable Guy" bit, then someone else would post Jeff Foxworthy and... I think that's about where this devolution terminates. Eric Andre is one of my new faves, but I think a lot of people hate absurdist style comedy (edit: the "skits" he does in public can be a bit too much). The stuff Kyle Mooney did before SNL handed him shitty scripts was pretty funny. Here's a sketch centered entirely on a jacket he found at a thrift store. You might identify more with this one though, 'bl00.
Which is never a fair criticism, because even when it's true it's like that story Brian Eno tells about the first Velvet Underground album selling very few copies, but everyone who bought one starting a band. It's a credit to what came first, but not a fault in what came after. But they're right that you can see Bill Hicks in a lot of comedy that came after him, and I think that alone justifies calling him a good comedian despite not being a good entertainer.
Don't make me trot out Yngwie Malmstein again. If you're a writer, Stranger than Fiction is a masterpiece. If you're just a schlub in the audience, it's that movie that Will Farrell is in and is somehow totally not funny but dating an exceptionally bitchy Maggie Gyllenhaal for some reason. The argument of articles like this is not "some people like Stranger than Fiction, some people don't" it's that "everyone should have the sensibilities of writers so that they appreciate Stranger than Fiction the way I do." It's still elitism. I'm not a standup comic, never will be, and don't even like to hang out with them. If I, the audience, don't appreciate something, it's not my fault. I'm just passively sitting here like a lump of shit. It's the job of entertainers to entertain. Maybe the audience is "fellow standup comics." That's fine. You still don't get to lash out at people for not appreciating the dark genius of Tom Green jacking off a horse.
