Carlin was original and to him 'words actually meant things'.
He was certainly progressive in his thinking.
@Livinlife What I liked was his ability to 'come down' on whatever line of thought made sense. He also lampooned some ideas considered 'Progressive' by the cattle on the Left.
@Silver1wun absolutely. He was intelligent and he questioned the status quo. He had the great talent of entertaining people while making them think at the same time.
