That is exactly the behavior he demonstrates. His ban here resulted from a litmus test he tried to apply to the members. If they didn't accept his conspiracy theories regarding 9/11 then they obviously weren't "honest" enough for him to bother talking to about Apollo. At JREF he escalated that to assert that anyone who didn't disagree with me as he did was similarly "dishonest" and not worth his attention.
Compare this with Adrian, who has played a similar full-court press against me, Ed Hegenveld, Dwight, and Eric Jones as "evil" people, urging others -- presumptuously even NASA -- to publicly distance themselves from that list.
When a person acts as if he believes there can be no rational dispute over his claims, then he is lost.
