i don't agree with "in private"
one of the Council member clearly shows a lack of civility, part of which is Internet etiquette (he most likely wouldn't have the aplomb to tell those things to people's faces...) and part being that he is an immature ruffian.

that (some of?) the other members of the Council don't like this behaviour and as the person doesn't seem able to grow up, the person as well is a sideline.
