they call it accentuating the differences

Not to flog my same old line, but here's a good example of where my general thesis seems entirely obvious. People can't hate Garfield this much. But they can desire to be seen as the kind of people who hate Garfield.

Update: Although, taking a good long look at Garfield comics for the first time in, oh, 20 years....

Update II: I guess it's a joke about responding inappropriately to bland corporate humor? Goes over my head.
