Orin responded to a post of mine on the Michelle Goldberg-Megan McArdle video.
First, I don't know whether Orin is objecting to my pointing out that opposition to Obama is often attributed to racial hatred -- something that I have seen again and again on MSNBC and on the internet (and even occasionally in Volokh.com comments) -- or whether Orin is objecting to my opinion that for some on the left this is likely a matter of projecting their own hatred of Bush and Cheney. In the clip I linked, I read Michelle Goldberg as defending the idea that the Tea Party movement is racist.
Second, I don't know whether Orin is objecting to my pointing out that some left-wing protests were astroturfed at least as much as the Tea Parties — remember ACORN, Moveon.org, and the AIG protests -- or whether Orin is objecting to my opinion that for some on the left this is likely a matter of projection of their own approach to organizing.
