What is actually more important is teaching kids critical thinking - which, yes, sometimes includes coming up with rational ways to collect and categorize information. In fact, rational categorization is a necessary step in lumping together 'like' things for our simple brains. This sort of learning will give kids the presence of mind and confidence to simply deliver a blank stare to people who like to argue "it's just semantics", "there's been a vote", or (most inanely) "get over it".
