MrsAbster has explained the role of the Chair perfectly. You have given an example of the appalling conduct that is sadly quite common in town and parish councils. In your position, I would have a quiet word with the chair and, in a non-confrontational manner, explain how disappoionted you were with his attitude and conduct. Maybe you could remind him of the Nolan principles? If this doesn't help, perhaps you or somebody else could notify the council of your intention to video the next meeting. Being criticised by an individual parishioner is a less daunting prospect than submitting ourselves to public scrutiny on YouTube until our dying day!
