No; you misread my post: the KKK had nothing to do with it. The ARA attacked National Alliance members, and innocent bystanders. The NA is about as far from the KKK as you can get: apart from the younger skinheads, NA types tend to have college degrees, graduate degrees, professional jobs, higher income, etc. NA types tend to be urban or suburban, not rural; middle class, not lower class; and more intelligent, and better educated, than anyone in the KKK. Big difference.
There are probably NA members or supporters who are as crazy/dangerous as anyone in the KKK, but I'll wager that even an NA loon is smarter than anyone in the KKK.
