That is an argument from game history. It's a perfectly valid point. Jonsu could make that point, but I haven't seen her make it yet.
This is not an in-game argument. It makes no sense for Jonsu to make this point.
See my point? Nothing forces you to accept Kharie in the Elder Council, but at least play the game, don't bring an OOC trump card to the argument.
There is nothing about that that is OOC. The form of government is COMPLETELY IC. Its in the name of the realm. Furthermore, Jonsu has her own motivations.
Also the majority of the Elders don't care if a theocracy periodically holds elections for its rulers, as long as its a theocracy. Apples and oranges.
