The data from our analysis comes from the National Consortium for the Study of Terrorism and Responses to Terrorism (START), a university research center partially funded by the Department of Homeland Security.http://www.start.umd.edu/
Our findings support the ADL statistic. Using their definition of right-wing extremists, we found that 92 percent of ideologically motivated homicide incidents were committed with a right-wing extremist or white supremacist motive.
What I did not see clearly defined in the article was the definition of which 'groups' were considered "right wing" and which were considered "left wing" and why. For instance, does the religious extremism of a muslim jihadi qualify as 'religious extremism' and "right" wing?
Those poorly, at least in my read, defined and delineated boundaries between who is what rendered the discussion meaningless.
Keep in mind the people who influence the scholars who study who is what, and you will find among them:
Mark Pittcavage, founder of the "Militia Watchdog" was an apologist for the Clinton machine and its actions at Waco, among other things, and was quick to paint anyone to the Right of Karl Marx as an "extremist". More info on him:
http://www.wnd.com/2000/01/1532/ he shares influence with such outfits as Morris Dees' SPLC which performed similar functions during the Clinton Administration, vilifying the right in general, and especially any group that stood up for the RKBA.
Unfortunately, both have shared undue influence on the assessment of various Law Enforcement entities, especially at the Federal level on organizations supporting Constitutional Government, the Bill of Rights, and especially the RKBA. I have little doubt that the conclusions and influence of those and others like them is appearing in the programs and materials discussing 'domestic terrorism', and who is considered to be a 'terrorist'. Note how often the FBI has swooped in immediately after an incident and declared it to NOT be a 'terrorist' event, and you see what's coming.
Unsubstantiated indeed.
