As the parent of an elementary school band member in Dennis Township, I don't have any problems with the teachers being involved in the concert. My own child told me that having the teachers involved makes the kids feel more comfortable and supported, and they think it's cool that they get to play with their teachers. Your comment about incompetence on the part of the teachers is offensive and unnecessary. You can express your opinion without being insulting.
