30 Rock was always going deeper. It understood the phony limitations of race even as it grasped how much a part of American life it is. This is what separated it from Chappelle’s Show, which grasped how racism was a fact of life — its glass-half-empty gleaning of race in America was the source of its nuclear power. But 30 Rock's characters' ability to live alongside each other is an acceptance that institutional and incidental racism and sexism and homophobia are part of how we live. We can survive by laughing at them.
