I don't think your logic follows. Unrestricted fights and restricted fights are both subsets of the set of fights, but restricted fights aren't a subset of unrestricted fights. By definition, unrestricted fights are distinct from restricted fights.

Either way, I regret pursuing this topic and won't comment on it further since I feel this is a discussion not worth having, reading, or writing. I don't write that to be rude, just as an attempt to hold myself to some standard for discourse.
