Why liberals think bigots prefer the Republican Party

Because they do.

Today at the supermarket, an asshole proud to be an asshole wore a T-shirt that said, "George Bush, Love him or hate him, he killed a ton of Arabs."

This is what the bullies want - not justice, not even law, they want to be the Whitey Bulgers of geopolitics. They want to be vicious, tribal, loyal, and most deadly. The ideals America was founded on? Who gives a shit about ideals? They want the realities - pogroms and genocide against native Americans, enslavement and abuse of forcibly imported Africans and their descendants, extirpation of all linguistic minorities, and elimination of everyone different in thought or behavior.

In short, scoundrels taking their last refuge in sociopatriotism.
