@lienrag No, I'm saying that some facts which are important to one person's understanding of a situation may not actually be that important in the broader context. They're fixating on issues they know sometimes come up and not questioning whether those issues are pertinent to the discussion at hand.
Oftentimes these folks have specific knowledge which they don't understand is irrelevant in the moment. So they're arguing things which don't matter and they don't realize it.
