I am very much of the opinion that a sufficiently complex and fervently held set of delusions is a religion, and visa versa.

The way these people act is very, very similar to how religious extremists act, in many, many ways.

Indeed, QAnon literally did merge with extreme rightwing Christians who convinced themselves they were actually modern day prophets, capable of magic (remember the crazy lady that yelled and shook a stick at a hurricane a few years ago, to send it away? QAnon prophetess), that they are literally waging a war against literal demons and demon possesed people, that Trump is literally a kind of messiah who is paving the way for Christ to return.
