I also maintain that stating everyone practices a religion removes any cohesive meaning from the term. I'm not going to say you're wrong, either.
So does stating that everyone breaths remove any cohesive meaning from the term breathing?
The definition does not remove cohesion. Rather, what it does is cause the cohesion to hinge on a
different paradigm. IMO, a much more useful paradigm.
Are we agreed that defining religion as belief in the supernatural is not an adequate definition, as it includes things that should be excluded and excludes things that should be included?
I would make the same argument for the dictionary definition of religion as a "set of beliefs and practices." Sorry but by that definition, the boy scouts is a religion.
The above definitions look at the outward form without understanding the underlying causes.
The fundamental intent of religion is to try to answer existential questions. It is an attempt to make meaning and identity. These attempts then get codified into beliefs and rituals, true, but the beliefs and rituals are the result, not the cause.
Religion is about meaning and identity.
