I'm sure that he didn't mean to do this, but Matt has a posting of groups that he thinks need to be censured before MoveOn. They include: Ku Klux Klan, National Vanguard, Prussian Blue, Aryan Nations, the American Nazi Party, NAMBLA, Westboro Baptist Church, pretty much anyone on this list, some of the various fundamentalist Mormon sects.
Okay, I don't know what he means by the Mormon sects, but I agree that the KKK and the rest of that list certainly merit approbation ahead of MoveOn. But did he really mean to include MoveOn with these racist groups? I am sure that it was an oversight.
However, Matt does have to admit that MoveOn has far more political impact than any of the other groups. Since their impact is so large, they need to be considered more seriously than the fringe groups that he listed.
Or accidentally included.
