You decide not to force your people to stay in your Duchy, but you send an angry letter - one of the n-th by now - asking they don't sow discontent in your lands.

Some few thousand people do leave your lands, and no riots occur. Your noblemen do bemoan and grumble at the loss of so many taxpayers and workforce.
983 AD, Mid-Autumn
Your wife gives birth to a boy! She names him 'Wynn', after a great conqueror of old.
Few days later you receive a reply from your uncles; their response is basically telling you to be more open-minded about people's spiritual needs, lest you suffer another religious war.
Also that they will proclaim whatever edicts they feel like.
Your noblemen are rustled with discontent.
"Your uncles from Ceodwell are making you a laughing stock, sire! It is time to act! We should show them the might of our forces!"
"Nay, our Army is weak and people angry after previous war. Let us ask our senior to rattle his saber, as Ceodwells seemingly are forgetting whom we serve!"
"Oafs! All this will bring us into further conflict with the easterners. We should instead wait few more years, so our people rest and our forces recuperate their losses!" Ultimately, the decision is up to you.
A) It is time for WAR!
B) Let's ask King Eón to diplomacize on our behalf.
C) For now, we shall do nothing rash.
D) Maybe send some spies to get dirt on Ceodwells?
