I might be talking out of my ass (again) but it seems to me that we've lost our sense of context here.
There's a whole world of difference between what we collectively dished out to get Tritone's goat and some of the more recent stuff. I believe many of the Black posters (XXXBit and BNLMike come to mind) agreed upon that point.
Lately, though, it's become a bit much.
Anything can be funny in the right context. See
George Carlin's take on rape, for example. But an obvious alt calling itself "Dead Nigger Storage?" Sounds like MPR to me.
