I really don't know enough about QAnon to say.

I have been ignoring them for the most part. QAnon ideas are just too absurd, so easily disproven, there is hardly any logic to it.
They seem to be more on the level of homeopathy or flat earthers; but those are not really cults.
It does seem to have some traits of a new religious movement; but I don't know where any of that will go.
