I find great truth in the maxim that righties think they have better ideas while lefties think they are better people. Ideas can be tested by logic and experiment. It can be difficult to judge a person’s character, and even harder to do so on the basis of bumpersticker slogans or blowhard talking points.
Leftism is much about identity and self-reassurance. This image lifted from the intertubes represents a whole class of self-congratulatory stickers, t-shirts, icons and other in-crowd swag.
Liberals are possessed of noble qualities, while conservative is a synonym for mean. And everybody knows Mean People Suck.
