There is a major problem with the definition of religion. Twenty years ago it was common to find the simple definition of “belief and worship in a supernatural deity,” in every dictionary. The problem being the definition is redundant. Belief is a form worship, and worship requires belief - does it not?
A person cannot worship something that the person does not believe in.
That definition kept atheists in a loop that continues to this day. It is a dogma that atheists have.
