But preaching is a crime in Keplerstan, the game mechanics simply don't recognize that.
There are things that the game will not let you do, because it would make a for a not-so-good game. Like randomly arresting any noble you feel like arresting. Or banning/executing any random prisoner of war. Or banning or executing any random noble belonging to an other realm. Or allowing game mechanics to enforce any arbitrary law that your realm may pass.
These are things which you theoretically could very well do, were this Real Life. But it's not. So the range of actions you can take are limited, in order to make a good game experience for everyone.
