Earlier quoted context omitted.
Yes, superstitions relate to supernatural things. Religion does too, in a way. That doesn’t mean it’s the same thing. Language is a lot more complex than that. And sure, you might derogatorily refer to someone’s religion as a superstition, just like I might call someone a “pagan” even if he’s strictly speaking just a heretic. But in reality these are all precise terms with different meanings. To be a bit more precise…
I touch (swear an oath and break it to) a rock (a god) and I receive luck (anger). Both are superstitions. The rock example is actually less superstitious because rocks actually exist. There is zero evidence gods exist.
It really has nothing to do with what you personally believe or not.
In your example the difference is that the rock effect is automatic, like gravity, but the god is a sentient being that has a will.
Why is it so hard to accept that people call these different things? You can still despise people who believe in both.
