I think so.
What is your query - not sure of how I categorise "genuine truther" or disagree that d.watts is a genuine truther?
I include two classes in "genuine truther" - both referenced to those who make technical claims such as CD at WTC. The two classes are:
1) Those who are honest, not deluded and hold genuine concerns abut the technical events but are open to reason and will modify/abandon truther nonsense in the face of reasoned argument. We saw lots of them back in 2006-7-8 very few now. I don't recall seeing one in recent years.
2) The various obsessed/deranged/illogical whatever. Who are so committed to truther concepts that they build impenetrable barriers to reason. Hence T Sz based on his posting here and observed elsewhere. His claims are technical nonsense but in the face of counter arguments founded in pure logic or professional engineering he runs away to personal insult. Will argue round in circles ad nauseam if people are prepared to ignore his technical contextual errors and focus solely on details. Multiple examples here of threads where debunkers have complied with T Sz's limitations of scope of discussion.
By my standards d.watts is a group 2 - genuine deluded truther. He believes his own delusions. For me T Sz is the archetype - he defines the class.
