I'm less worried about online forums and more worried about how sometimes we take things so personal. People on this board are always talking about airing up the tires and jumping ship from parents or admin or lazy students. Yet we claim it's OURS? Meanwhile, the folks that are vested with home ownership and maybe even business ownership in the community have a much bigger stake in the organization than the director who might roll out at the first sign of trouble.
Towns that support their bands and athletes and schools have many more people NOT involved in school than are yet those programs belong to the community. How many folks are sitting in the stands on Friday nights with no kids in schools? How many are talking about the game or the band at the grocery store with NO kids in the program. Maybe they had kids or will have kids but currently don't. Those are the folks that the program belongs to. Pro sports are another example. a few thousand work for the Astros, 1 person owns the team, and yet an entire city claims them as "theirs".
Worry less about the perception on a public forum and more about the perception when folks will look you in the eye. Keyboard warriors are brave but those that will look you in the eye are true.
