Politicians, local ones particularly, serve as objects of abuse from residents upset about any number of things.
Sometimes those complaints are ridiculous; sometimes those complaints have merit. Sometimes they are stated with respect. Most times they are not.
Regardless, people who make those complaints have a clear right to make them. It would be better for the city if more people attended council meetings. It would give the council a better perspective of the community if more than the standard handful of people were to make their comments during the public comment segment.
