He's not all that liberal. His books are filled with Anti-PC rants that would make some liberals' heads spin.
Yup. His anti-PC stuff is truly great. He's an equal-opportunity offender, always has been.
Carlin's something of a libertarian on many issues, but leftist-populist on others. Odd combination. Sometimes the guy's hilarious and right on, other times he's waaaaaay off base. I have some of his albums and enjoy them, others I avoid.
