I'm not calling people that prefer mmp knuckle draggers I'm calling NZers knuckle draggers in general. Maybe a bit harsh but I'm speaking with emotion here too. Anyway, because of that MMP wins by default regardless of merit (and it has merit of course).
But STV seems to be more granular and possibly more representative with less wasted votes. But due to it's complexity vs the knuckle dragging thing I'm sure we'd find a way to fuck it up.
