I disagree with Carlin on many high level ideas (religion is a big one), but he was a brilliant observer and wordsmith, and still hilariously hits so many social nails on the head, even when I disagree with him, I'm usually still laughing. Even the cursing, he's not just dropping random f-bombs, they are intentional and meaningful, as opposed to so many whose vocabulary is 95% four letter words.
This appreciation/discussion brought to you by tubitv, which has a bunch of Carlin specials and best of shows, and comes through the work firewall. Looking at "You Are All Diseased" from 1999 right now. Him talking about overcleanliness being unhealthy is great right now with the kung-flu paranoia. Don't know if everything he's done is there, but there's plenty to chew on. Comedy that makes you think is hard to find.
