And there are no tool collectors? I also collect beautiful tools. (E.g., old timber-framing drills.)
There are tool collectors, but they are demonstrating "collecting behavior".
In Boy Scouts we were taught to respect and appreciate guns as the very dangerous tools they are. I can personally only agree with your original statement: Guns -are- only tools, and should only be treated as tools.
You appear to contradict your statement that "Guns are just tools".
