perhaps you never heard that McVeigh was working with MUSLIMS in OKC and Jayna Davis wrote a book on it called THE THIRD TERRORIST?
Perhaps you never heard that Eric Rudolph was always considered a LONER and a religious extremist who was rejected by every church that existed and had zero followers and therefore is NOT what the subject is about?
Gordon Kahl and Robert Matthews who?? If those guys were so famous and Right Wing militia types and so dangerous, why arent their names known like McVeigh and Rudolph?
Whether or not any of them were "loners" or poorly socialized, or even if Davis' speculations were believable, it would not change the fact that all four were products of the constitutionalist/militia/patriot movement.
If you don't know who Kahl or Matthews were, it really doesn't matter - they are well known to history and to the families of the people they murdered.
