His arguments are:

1) If you don't do science through the establishment, then you are not doing science.

2) Only people trained in universities can be trusted to do peer review.

3) Bush was running the government (and not the DEEP STATE) and Bush's only objective was not "you are either for us or you are against us". He entirely sidesteps the point of 9/11 was to foist  "you are either for us or you are against us" on the entire world. And he substitutes a strawman, Hegelian dialectic for logic. He sidesteps the concept that the DEEP STATE plays many different elements against each other in order to retain control.

In short he is either knowingly acting as a gatekeeper, senile, or just not that smart. I would bet on the first conclusion.
