"the mayor is making a mandate"...
wait...I have a mayor!? since when?!
and a captain of the guard also. what the hell...
i alway thought nobles came with immigrants, never thought that the "expedition leader" would evolve like a pokemon into a bitchering noble...going to magma him.
but i can't. she's a woman. a married woman, with child, who is also my captain of the guard. Now that's favoritism.
Now, that's Fun®, you mean.

A more diplomatic way to do it is ensure the mayor stops seeing people. Lock her in a part of the fort with clever use of burrows, and dump enough stuff for her to survive. Soon enough, her social skills will deteriorate, and another dwarf's will pick up. When there are enough idle dwarfs, a more social dwarf will be elected in her place, and she will be able to leave her burrow again and become a harmless civilian.
That, or you can just [r]eplace her, which will only last as long as the next elections, anyway.
