It doesn't really matter though, Dharma is still a superstition. So is not changing socks when your baseball team is in the championships.

Trying to parse it from other superstitions doesn't change the meaning or existence of the word, nor the fact that it's still classified under that category.

Speaking for myself, religion/dharma is not hurting others and being honest. It's not based on superstition, it just makes me feel happy. Happy is healthy.

Point being, the meaning of these terms are too broad to tag & generalize them with a few words.
