Q-Anon is a dangerous precedent and shows just how easy it is to manipulate people. There are lots of people out there busting their asses every day, not making a lot of money, and they think these rich lawyers in DC give a darn about them, when those lawyers pit them verses 'black welfare queens' and LGBT.
I think the reason why trash like Q-Anon seems to easily manipulate republicans is their emphasis on religion. Not the religion itself but "the next life and personal salvation" part. It seems to be given priority over service to the state and civic participation. When you internalize life you tend to not see the forest for the trees when you are the tree. At least that's what I see in my evangelical wife.
I'll make my exit.
I'd put it more generally. If your willingly believe in magic (most religions) you'll believe anything.
