Is David Ray Griffin a Neo-Con Agent?

(Note: Be sure to read the clarification at the end of this post)

At one time or another everyone in the 9/11 denial movement will get accused of being a "disinfo" agent by one fellow paranoid or another. Now it is David Ray Griffin's turn.

Some guy named Progressivephoenix writes:

Dr. David Ray Griffin, the author of several books that claim to debunk the official 911 theory, is in fact a charter member of the neocon movement. He is a member of the Disciples of Christ, a far right-wing christian group that focuses on unity among Christians and "restoration" of Christian dominion. The sect is associated with the Reverend Jim Jones, who massacred over 900 people in 1978.

He attended a little known school called The Claremont Colleges in Claremont, CA. The Claremont Colleges are is the current intellectual center of the neocon movement. Neocon mouthpiece, The Wall Street Journal called Claremont, "the intellectual capital of the western world." Dr. Harry Jaffa, professor emeritus at Claremont, is the world 's foremost interpertor of neocon founding father Leo Strauss, and a former student of Strauss.

Griffin indignantly defends himself:

This little hit piece by “progressivephoenix” (which I will abbreviate “PP”) is too ignorant and silly to deserve a reply. I have, however, been asked to respond, so here goes.

PP obviously has a far different standard for “incontrovertible proof” than I do. The remainder of my response will explain why.

Now I actually agree with Griffin that the attacks are baseless ad hominem attacks. But I have to ask, how is this different than claiming that the Popular Mechanics book is "semi-official" propaganda based on the speculation that Benjamin Chertoff and Michael Chertoff might possibly be distantly related, or attacking most of the US science and engineering community based on the fact that some of them rely on government funding?

(Note: We have received an email from the person who apparently wrote the original post claiming that Griffin was a neo-con, stating that the post was intended as satire. Of course this reveals the problem with satirizing the 9-11 Deniers; satire requires taking a position to an extreme, but you cannot get more extreme than the kooks.)
