Why put yourself in that position? I understand the passion and emotion. Next board meeting, start passing around a recall petition to have the entire school board replaced.
If there is no recall mechanism demand that the city council put one in place. If they don’t, recall them.
Start over.
The city council has nothing to do with a school district's policies or actions nor do they control them. The school districts are their own entity. People where I live are always contacting the city to DO SOMETHING about the school boards/districts. The school districts within the city limits merely have to follow the local laws but beyond that they have their own elected boards just like the cities have.
