I think ultimately you're probably right, but I wish that wasn't the end-point of the analysis, if that makes sense. It shouldn't be good enough. I understand it's possible people's brains are short circuiting because they can't find a rational reason to be pissed off, but why it has to jump into bizarre alternate reality conspiracy theory, and why it's okay to talk about these things in the mainstream (or maybe history.com isn't mainstream, maybe the whole internet isn't mainstream) just baffles me. The argument seems to boil down to "black president does not compute, therefore craziness", and it almost seems like making an excuse for the behavior on some level -- like "oh, they're racist" is an end-point conclusion rather than opening that up and saying hey, this is not socially acceptable (the behavior, with or without racism). But I ramble.
