Other than if someone tries to tell you institutionalized racism in the U.S. is dead and buried, you should feel free to laugh very hard and call them a dumbfuck. I would, however, draw the line at hitting them over the head with a very dead rat. It might splash on you.
Ditto anyone who holds up Gov. Jay "Taking A" Nixon as a potential Democratic presidential candidate.
Oh. And anyone who claims we can eliminate these incidents with this one weird trick (I'm looking at you TNR).
