Except that you figure that people that are 100% happy, 100% loyal, and not having any seditious thoughts would not "dislike being ruled by us". A better wording of "would prefer to be ruled by another" would make sense.
I'll check that out see if it makes any sense... As an ambassador, I could try to fix this, if it really is the case.
If it is accurate, I can't believe this was coded in before ambassadors were even put in. It's kinda douchebaggy (sorry to whoever did it) to implement such a harsh mechanism over a variable players have no control over. Priests hardly count, as their loyalty tools are pretty awful.
