I don't know who invented the phrase, was it Charles Krauthammer? He certainly had a head start on most of us with his 2002 piece Stupid vs. Evil? To wit:
To understand the workings of American politics, you have to understand this fundamental law: Conservatives think liberals are stupid. Liberals think conservatives are evil.
Kathy Shaidle gave us a Christmas present last year with this inspired piece, Right-Wingers, Please Stop Saying This One Stupid Thing:
But there’s one expression that’s been in heavy rotation of late, for obvious reasons, and this one especially has got to go:
People on the right think that most people on the left are wrong; people on the left think that most people on the right are evil.
I, for one, think most people on the left are evil, not just the useful idiots, well-intentioned twats, and downright dupes the polite right always wants to provide cover for, for whatever weird reason.
If you prefer a less abrasive word than “evil,” then try “sinful” on for size. What else do you call those who want to steal your money and destroy your life? Who compulsively lie? Who are fine with Muslim slime raping other men’s women (or even their own) as long as nobody calls them “racist”? Who consider abortion a secular sacrament?
When you look at the way lefties have fallen all over themselves to cover for their wire tapping henchmen it's hard to argue with it.
Meanwhile, Kurt Schlichter doesn't beat around the bush: The Left Hates You. Act Accordingly.
