Haven't watched it, I didn't really watch his earlier stuff either tbh -- although I heard about it because of the media splash.
Maybe my perception is wrong but from the discussion it sounds like his targets generally were the disaffected and minorities that are already abused by the system and who do not possess power realistically in the system. Typically comedy makes a better splash when it's used to tear down established powers and those in control. It's a weapon for change for those with no power in the system.
I'd have to watch the show to get a better since of the nuance, so my initial thoughts could be wrong here, but: Maybe he perceives a threat from previously ignored voices who now might have more power on social media and would potentially try to control his speech, but damn... when you're in a minority where you run the risk of losing your job, your housing, your religious affiliations/community, your family, your ability to support yourself, your ability to just be considered like everyone else, and then some guy jumps in to reinforce the same social stereotyping shit that is keeping you down once your community finally has been finding a voice... how is that not a douchebag move? Or a guy who is just more interested in his own career and "freedom" than the ability of his targets to finally find equal footing in society?
I liked it! I wonder if some media outlets are panning it because Dave is going against the grain of their narrative.
I am pretty sensitive to gender stuff since it's something I've wrestled with for a long time, but I still quite liked the car ride analogy for LGBT. I think it was pretty nuanced in comedy to make the point about how despite the fact that many people think of LGBT as a monolith there are differences between the groups/identities and little resentments. I cracked up when the Q saunters up to the car in booty shorts, not sure exactly what they want, but gets in the car anyway.
I was made very uncomfortable about the parallels between the black crack epidemic and the white opioid crisis, and the white hypocrisy, and I appreciated being made to feel uncomfortable. Shook a few things loose for me. I did not feel comfortable in my whiteness watching the special, that's for sure! So I wouldn't see why Nazis would be into it.
All in a day's work for one of the best working comedians. I wouldn't call it his all-time greatest work or anything, but it was relevant!
If he was targeting everyone, then that's definitely better than the buzz I have been hearing.
Can't really comment further because as I have admitted, I haven't watched it. My concerns are simply what I've stated, but I would revise once I would watch.
The thing is, I've watched a bit of his earlier stuff and was kinda "eh." Some things make me laugh, I don't remember being particularly amused by him. Maybe he's just not my thing. So I'd only watch this special as context for discussions, which means it probably won't happen.
I can't believe that 99% of audience members approved of his performance.

It's such a stark contrast to the critics score.
ha, maybe you didn't notice how it's been for awhile... Pretty much when they reset the scores in Netflix and Amazon to reflect an audience baseline and not a critical one, I pretty much can evaluate whether I will like something based on the inverse of the score. 5 stars? It probably sucks. 2-3 stars? Woot -- I'm gonna love it. Not EVERYTHING is that way, there have been works where the critics and audience align have similar appraisals, but it's a minority it seems.
IMDB meanwhile has always been heavily skewed towards white people and males; also, the popular blockbuster films/works.
