None of the things by themselves fully justify “belief” in a religion yet many people claim they are without a true belief in the entire system. It’s the problem with such a vague question. By a narrower definition very few people attending a place of worship are true believers. Someone can believe in god, but not really believe in the rules, and still say they are “religious”. Someone can believe in the rules, but not god, and say the same. I think if you are practicing the religion to some extent then you have a right to call yourself religious if that’s how you view yourself regardless of your true beliefs on god, rules, etc. Cultural impact matters more than we give it credit for.
My sister in law is blind in one eye, but because she has one working eye she has no disability protection as far as I know. She still can’t drive because she has no depth perception and it’s very dangerous. It’s made navigating going to work difficult over the years, often working the same place my brother did so he could drive her. Luckily her current employer works with her and lets her work from home. But a decade ago no one would have dreamed of letting her work from home.
