I think the author was mostly interested in this short essay to let them (Vernon Jarrett, al-Mansour, Percy Sutton et al) speak for themselves re political ascention of otherwise obscure Obama and unveil the links to Arab money funding the "education" of "underclass" in the U.S.
You are right about the author’s intent.
You will go insane if you attempt to unravel all the interlocking relationships between commies, fellow-travelers, useful idiots, and all their shell/front organizations. “Discover the Networks” does a good job trying to do this, but it is thoroughly mind-numbing. If the author had tried to extend his thesis to commie relationships, the article would have been even more difficult to follow.
