I think you are severely underestimating the intentions of people when they visit places like this. There is 100% a religious or spiritual element that causes these people to go and seek answers at places like this.
And I have seen multiple times where people get hooked on these types of practices or make really bad life decisions because of the bull crap they hear from them. I know one lady who even divorced her husband after cheating on him because of the advice of some of these people. Another landlord I knew up in the Pacific Northwest would consistently visit one of these false people. She would get told that she was someone extra special in a previous life or that a friend of of hers was secretly being punished because he was a Nazi who executed her or something stupid.
Like I really want you to understand how demonic and outright cringy these things are. The people who go to them are not simply looking for a Disney-haunted mansion experience
You sound like a wonderful person. I appreciate how there is no hiding your own religious hangups and inner tension and the way you superimpose this struggle onto others.
