I listened to a little of his latest - tho not the one you mentioned - online last night and I agree it is slash and burn but it's applied IMO to everyone across the board: Left Right and Center. He turned himself into a social critic.
As far as elevating him.....I find that funny - "Carlin spinning in grave over posthumous adulation"
I agree he was an equal opportunity hater. I listened to his routine “I Used To Be Irish Catholic” it was funny. Yes it did have religion as its subject, yes he did not spare anyone his wit. It was true and biting. It had wit without malice. The difference was Carlin in those days was everyman. Looking about the things of this world that plain as day did not make one bit of sense and calling us on it. He invited us to join him in leading the sacred cows to the slaughterhouse. He woke us up.
But his later stuff was so bitter it was more a case of George Carlin against the world and everyone in it. And that meant his comedy became a form of attack rather than a form of illumination. And that is too bad. I hate to think he died with such anger in his heart.
