> In retrospect, my correction to her should have taken the angle "That's kinda like calling a Chevy Cavalier a 'limo', or a 'Rolls-Royce'. Yes, it has 4 wheels, a hood, a trunk, a motor, it drives on roads... And the Chevy fans and salesmen are talking about how great it is...but NO, it NOT a limo, and NOT a Rolls-Royce." As someone who does not drive, I would have a difficult time identifying vehicle types beyond half a dozen very broad categories. The only reason why I can do that much is because I am literally surrounded by them. The only real difference with warships and tanks is that I hope I am never surrounded by warships and tanks. The point is, the nuances of classification are typically of interest to people who have an above average interest in a topic.
