At least if they have a subjective experience, they have some kind of reason for believing, you know? In contrast to most religious people. Also, one of the most respected left-wing journalists in my country has said he has had some contact with God in his life. And he's probably the person in media I respect the most, and he's a remarkably decent dude.
But I hear you. It's a bit scary
You are giving this way more thought than I think you need, but hey it might work out. All I know is that, being in the South, you see a ton of religious people who are on some shit. Some are condescending. Some are duplicitous. Got no time for that at all.
