Humor, particularly satire, is often pre-selected by us. We like what is comfortable with our values, our religious beliefs, our sensitivity over sexuality or violence.  Some like slapstick, others not so much.  There has been a decline in "wholesome" humor of late.  No more Sid Cesar or Carol Burnett or Bob Newhart, that made us laugh just because it was funny on a very human level.   Pretty much all groups look at others as having deficiencies.  Urban elites look down their noses at the small town, but it goes the other way as well.  We are not They, and They are not as good as We.
