I would like to elaborate on that, actually.
One of the hallmarks of tax protesters and so-called "sovereign citizens" is that they do expressly or impliedly and
falsely claim to know the law better than the experts on those subjects. Almost uniformly, these crackpots believe or claim to believe that 99% of all the experts on Federal income tax or law in general are wrong, and that they, the tax protesters, etc., know better. This is not only arrogance of the highest order but is also an exhibition of
lack of intelligence in some very practical sense.
By contrast, Dan (and others) who opine that tax protesters, etc., lack a certain level of intelligence are
not claiming something that contradicts the great weight of opinion of those who are experts in the field of the study of intelligence. Granted, there may not be any studies of the intelligence levels of tax protesters, etc., as a group. To my knowledge, such a study has not been undertaken -- by experts or by anyone else. But, neither Dan nor the rest of the regulars here are claiming that we "know" something about "intelligence" that contradicts the knowledge of any real experts on that subject. Dan is being neither (A) being arrogant nor (B) claiming expertise the field of "intelligence" by rendering his personal opinion in this case.
Further, I don't think it takes an expert in the study of intelligence to point out that virtually all tax protesters, etc., are exhibiting monumental stupidity when they pontificate so foolishly and cluelessly about the subject of taxes or law in general.
