Pretty much.
The few times he tried to step up in the 9-11 thread wars, he would get maybe a paragraph into some vaguely held belief, get it spanked, then ignore the spanking and throw the next thing at the wall, get it spanked, and so on. Just like every other conspira .
He thinks his beliefs make him special, and are a source of self-esteem, so at the core, he is unable to really give them up, IMO.
Delusions can be very resiliant.
