Quality of discussion is in my opinion mostly based on mutual respect. As regards that, if we trust each other in basic statements, we will simply agree that experience can be vastly different.
Not only having experience with multiple characters, but some of my characters moved much, so they "covered" many realms.
For instance, what I saw in multiple realms in current times, habit apparently transmitted throughout continents over time: in monarchy ruler elections, there are often one or more nobles who call ruler candidates to state their "program" , and they even structure such demand into several specific questions.
Once I complained publicly that ruler is to be elected on basis on his previous deeds, his established respect with the realm, apparent qualities, claims etc. as monarch as a concept assumes that elections values those fundamental values of chivalry that would guarantee realm's future, not some "program", especially if ruler candidate may not think such specific questions are the most important ones. And somebody called me "non-democratic".
The fact is if there were buttons strong enough, some players who may not grasp concepts from very beginning would better do it when faced with in-character harshness.
Currently, I am often reluctant to conduct deep discussions about noble values, to apply arrogance toward younger nobles, insist on claims etc. as there are so many angry reactions which often turn to ooc. Absurdly, the more convincing my character is, the more ooc upset some people are, though it is really funny for me that when I say " you are incompetent young noble and your low reputation barely allows you to ride a horse", somebody takes it ooc.
If I pursue such behavior long enough, most of people get it, because of the fact that most of Bm players are clever, some just lack wiki reading and initial player guidance, and they spent many months without grasping basic concepts.
The same parallel can be drawn with realm council buttons - they would help players to better, quicker and easier understand what tyranny, monarch etc. is, they will barely understand anything if seeing ruler is trying to please them.
At this point I can also ask myself where you draw your experience, probably within some of large and long-established realms, where changes in game mechanics did not affect players habits.
And I really needs to disagree with your indirect statement that there is no enough means to get rid of council members.
Let us take some tyrant as and example. Would it be realistic that few protests can take him off the throne? Certainly not, what would be his power than. So there is option of either mass protest or well-prepared rebellion that does not have to have extremely much nobles involved. Or persuading strong dukes or other council members against him... So vast number of oppotunity which give chance for funny.
But it is actually not so funny to overthrow someone who is not powerful, lack of such buttons simply sterilizes game in many aspects. I am almost convinced that if council members have more power, they would be attacked more often.
