Driftglass nails it:

"And if you're one of those people who has spent your adult life supporting these degenerates while sneering at those soft-headed Liberals and their crazy ideas, maybe after 35 unbroken years of being horribly fucking wrong about everything it's time for you turn off Glenn Beck, stop whining about imaginary hippies, go down to the basement, pick out one of the 78 guns you have stashed there to protect you from the Coming Race War Or Something, and do the honorable thing."
