Met a few people who say this and I know there are different schools of thought on this topic. Thoughts? Can you believe and not be 'religious'?
Well where do they think those ideas come from? Organized Religions. I think they just want to make themselves sound more credible.
It is semantics. Maybe they say they are not "religious" because they think they have a "personal relationship" with the invisible man in the sky. These are often the pious. By most people's definition they are religious. Though their piety, delusional thinking, and self-rightousness leads them to think that they are something beyond that...
