Gag me with that dimwit stuff. Produced for the democrat urban crowd.
When it comes to today's TV, there's a lot of truth in what you say. But most of the characters on that list are from the 60's and 70's. Sure, some played dimwits. But most didn't. Spock, Lt. Columbo, Oscar Madison, Jim Rockford, etc. ... hardly characters for the democrat urban crowd.
