I think most people have an 'is X Primal' question sooner or later, I think it's normal. Probably because we've been taught to question CW, and so a lot of things we took for granted we now consider wrong. The metaphorical rug has been pulled, so to speak.
Plus, some people like clarification on every aspect of their lives, some people are more easy going. General questioning of a something seemingly benign is probably how primal/paleo started in the first place.
