Do they? Alex Jones is a Democrat?
I would say that low iq magic thinking people own "911 was an inside job". Many of these people have multiple conspiracy theories at once (flat earth, YEC, anti-Vax, etc....). When evidence is removed as requirement for belief, all kinds of crazy can result.
You should be aware that this magical thinking was an absolute requirement for survival when man fended off predators with only a rock. Homos that thought too long got eaten. That is the hypothesis at least. I don't believe that magic thinking provides an evolutionary survival advantage any more.
