What should be really scary is that people who believe in any kind of magic(celestial bodies governing your life, wizard man in the sky) will believe anything, because trusting something with zero proof is so familiar to them.
In my experience, having contradicting beliefs if pretty common and people are pretty good at mental gymnastics to create a justification that works for them. Or they just change their beliefs, many people change their faith.
> Especiall since many of those beliefs directly disavow each other.
There was no problem with that in the past. Like, “Jesus loves everyone, except if you’re gay”. Or “don’t kill, except when taking the wholy city from muslims”. I bet if we dig deeper we can find more examples.
