You see, MacDonald has written many books on Jewish social evolution. He is applauded by white supremacist groups all over America and Europe because of his views on how, why, and when Jooooos have taken control of the media, the banks, and have changed "white" culture wherever they went.
You get the idea that MacDonald believes his findings are scientific fact, but they are only based on Joooo paranoid speculation. The only thing scientific about his studies is the FACT that Khazar theory is bull crap. That kind of stuff can be studied scientifically using gene research.
Tillawi obviously didn't research his guest very well. Instead of just piling on the rhetoric that Jooos control the US senate and that is why the US supports Israel, he got toasted by the fact that MacDonald's research has debunked Khazar theory. Tillawi's reaction in the interview is priceless, because the biggest contention the Paliphiles have is their idea that most Joooos are Khazar and their ancestors never set foot in the middle east.
White supremacist sites often quote MacDonald, except for the Khazar part. And MacDonald himself, is a Judeophobe who either won't face up to the fact honestly or is too stupid to realize it. He went to bat for David Irving, on the basis that his mandate to do so, was free speech.
To be honest, I agree with some of MacDonald's findings regarding reasons for success and intelligence, but I think they go way too extreme. What he misses, is that the reason Jews appear to have control is that on major issues regarding ethics and morality, the average Jew meshes very well with Western morals and ethics. At least, what the majority in the West want. The West is capitalistic, and if collectively, they didn't like what the media was saying, or what was on TV, etc. Jews would just go broke:) The main reason that the US supports Israel is because once you strip the irrational Jooo hating, you are left with a state that pretty much represents Western ideology.
Here is an article on the controversy of MacDonald as a university professor.
MacDonald's views on genetic isolation is controversial, but it does carry some merit. Too bad he didn't talk about it with respect to the Arab Muslim world.
