I think you're confusing "Simulationists" with people who refuse to play a game unless someone can explain it to them in a way that makes sense to them. They'll refuse to use Action Points or Warlords that heal because "That doesn't make any sense." or "That's dumb." I'm pretty sure there isn't an official Forge term for these types (or any polite term, at any rate).
As a Simulationist, AP don't bother me. I can justify them as adrenaline or "innate magic", but frankly it doesn't matter. I take the game world as it's given to me and I see where it leads in an emergent manner. AP are a known factor, every PC and many monsters have them, and the world does not "break" if you try to use them in a way that the designers didn't mean for you too (unlike Minions). They're cool.
