One of the requirements <b>isn't</b> "nationalism". Go look.
The Turner Diaries was rooted strongly in the fucking nutjob movement. I'm no big fan of Christianity, but I still don't believe a labeling of McVeigh as a "Christian Terrorist" is accurate (whereas I do believe a labeling of Mohammed Atta as an "Islamic Terrorist" <b>is</b> accurate) - his act was not induced by religion, but instead a pretty strong dissatisfaction with the United States government.
I'm sure we could all come up with a better person or group to label "Christian Terrorist(s)" - I just think McVeigh is an awful example. And that's all I was pointing out.
