The author here clearly is extremely superficially familiar with the writings of rationalist people and views them from a preconceived standpoint. Comparing beliefs of Yudkowsky to dianetics is nothing short of misguided, whether you like him or not. This is a textbook study of motivated reasoning.
Aren't rationalists supposed to be objective and motivate their claims, rather than belittling any critic with unsubstantiated statements?

What would be his motive, why would he have preconceptions about you?
Could it be that it's your messages here that are motivated, and with scarce reasoning?
