Yeah there are definitely some earnestly religious people.
I just think that material circumstances, group identity, social status and things like that are what determine the behavior of social primates. Religion is a convenient explanation because it makes you look upstanding and can justify absolutely anything, really.
We’re definitely capable of some amazingly counterintuitive behavior - things like moral panics, groups who make high risk travel, or high control cult groups. But again I’m not convinced that religion is causing that. A lot of those things have non religious examples as well - large parts of the cultural revolution sounds like a secular mania to me.
I still suspect these sorts of things are just human behavior. Even if we finally cast off religion for good, I fear we’d still see all the same things happening just with different explanations.
