Another thought, you can go all your life without being exposed to conservative philosophy, but unless you're Amish and eschew all education & Hollywood & books, you can't go through life without being indoctrinated in liberalism. Conservatives are more well-rounded and can poke fun at themselves. Liberals cling tightly to the dumb hickseeds mentality.
"Knowing a lot" doesn't do you any good - if what you "know" ain't so.
