If they are trying to get something religion can not provide.
Some people think that God is going to give them what they want or if they pray the right way God can be bribed into giving it.
Religion is simply a type of philosophy. It's suppoed to help you improve yourself and your life.
People are lazy, they don't want help, they want magic.
Delusional people can be one's who think there are ghosts out there. If you think there are religious people and ghosts then they are one in the same.
If they don't respect division of church and state.
Depends on why they are religious? I know people who are "religious" because going to church is something that they've always done and it's how they learned to socialize. Being in those circles and socializing with familiar trappings helps them deal with the world. They are happy that the really complicated questions about reality can be put in a book so that they can go on with the daily mistrations of living in our world. It's easy because nothing really complicated has happened, nor have they experienced any hardships in their lives, to make them question what they get from their beliefs. I would say these people are not delusional.
I also know people who are religious because they strongly believe in the reality of their god, and the belief that their god actually interacts with them personally and with others in their lives. That their god does things for them personally based on a belief, prayer or offering of some sort despite the fact that there is no real evidence to support it. To me, that's delusional.
So, I find most religious people to be someplace on a spectrum of the non-delusional to the delusional and their position constantly moves based on what's going on in their lives in the present.
Finally, I find that the delusion, at least AFAIC, to be more related to their belief in a god than their tie to a religious organization.
Certain theists insist that a snake spoke.
Certain atheists agree too, but the snake only said one letter several times
"ssssssssss"
So, yeah, I would agree that if people of the book. ( all books) believe such theistic stories, then they're delusional in this aspect.
Yes, especially the super devout and ones who take religious texts literally.
Thank you all for your responses! Glad to see that I’ve joined such a flourishing and intelligent community!
Yes. It amazes me how otherwise intelligent people can continue to belive such nonsense.
