Or, the specific example that came up today, "Don't define, just be!" in response to, "I'm trying to get a handle on what the difference between a 'submissive' and a 'slave' is, can anyone help me understand how these words are used?"

Eh, I gotta admit to a little bit of sympathy there, but only because many people's definition of "slave" is so obviously a bizarre construct built out of generic wankfodder, Story of O, and Gor.
