Christianity, Judaism, and Islam are superstitions. Buddhism is if full of superstition. African diasporic religions that involve ancestor veneration and divine spirits are based on superstitions. The main religions of India; Hinduism, Sikhism, Jainism, and Buddhism depend on blind beliefs and superstitions for its existence. Please, if any body can tell me, what religions are not superstitions?
"Are all religions superstitions?" To me that's like "Is the pope catholic?"
I always figured that "religion" and "superstition" were somewhat synonymous. Well, you can have superstition without religion (don't break mirrors, don't split poles, etc.) but I don't think you can have religion without superstition. I guess it's more a parasitic relationship rather than symbiotic.
