Qanon is, from what I’ve gathered, one or more assholes who use the human condition of gullibility (i.e. generic “faith” in this case) to sling nonsense and conspiracy theory to charge the simple-minded.

For example, the cult of personality of Trump is highly supported by Q. It’s basically a lightening rod for people who want to ignore reality in pursuit of whatever bs they want to believe in any given moment.

So the term red-pilled means what you said but it has a very hard right wing lean to it. It’s often a rallying point for fascist and the like. This is my understanding from what I’ve gathered over the last year or so.
