If you could do better, go and do it. If you couldn't, or are not prepared to, Shut up.
S,
Happily agree with the first part of your statement, however can not do the same with the latter.
Those in office of any organisation or club have the duty to discharge themselves of their responsibilities in the best way possible.
If the membership of the club has founded concerns they should be able to vent them in a constructive manner, stating that you can just 'do it yourself if you know better' holds no water.
