Charles Johnson at Little Green Footballs has apparently decided that the problem with the conservative movement is that it needs more purges, and Pam Geller at Atlas Shrugs seems to be his designated scapegoat.
Long story, but it has to do with the Euro-Right's stance on Islam and immigration. Continental politics involves coalitions and loyalties that do not translate easily to a U.S. right/left understanding. European nationalists, who are the only organized opposition to the Islamic influx over there, do include some unsavory types, but if the alternative is Euro-jihadis and honor killings . . .?
Pam is a good person and I would suggest that this guilt-by-association "urge to purge" is antithetical to the best interests of conservatism. You can't build a movement by the process of subtraction.
