Hey, you, the person reading this. Do you know what it means to be a liberal? Depending on your own political persuasion, being liberal might make you a firm believer in liberty, equal opportunity, and the right to pursue an economic system that distributes the benefits of capitalism more broadly across the citizenry. Or, being a liberal might make you a Stalinist, Marxist, atheist, pantheist, freedom-hating, abortion-craving, tree-fondling, Chick-fil-A scorning, queer-o-sexual menace to Jesus and the Constitution that He wrote.
Either way, liberalism inspires passionate opinions in American society.
