Ditto Howard Zinn. These people are poison.
I might add figures like the Smothers Brothers and Norman Lear. Not because they are necessarily evil but in their own way they changed the media and popular culture. They made it the norm for “entertainment” media to become very political and try to shape the public attitudes. I am not saying sitcoms and other TV shows had to remain totally vanilla and family oriented. But the left wing stuff they have peddled for decades now has no doubt demonized conservatism and made it that much easier for Dems to win elections. This gives them such a built in advantage that the right has to fight that much harder.
