"Saying 'yes'" isn't GM force. It's not GM force when a player in an AD&D game says My character wears a red cloak and the GM says OK.
@Lanefan , if you don't understand why "saying yes" isn't GM Force by now, I'm not sure this will do any work:
GM Force is the willful subversion of a player's "say-so" with respect to the gamestate (that is the most abridged version I can muster). "Saying yes" cannot subvert a player's "say-so." It is definitionally acquiescence. Hence, it can never be Force (regardless of how you feel about the player's "say-so.").
