You don't need to be confused, you can just talk to the person about something else for a bit to determine they aren't an imbecile, then verify their view is actually incoherent by talking to them about it, then write them off as part of the growing group of people that are choosing a fantasy they want to be true rather than the verifiable actual truth in front of them. it's pretty easy to suss out the situation by determining which of the 3 I's you are experiencing (imbecile, irrational, or I duffed it and had my mind changed by talking to them).
