People complain about complainers.
However, one of the founding documents of the United States of America, the Declaration of Independence, consists mostly of a list of 27 complaints about King George III:
"He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our people and eat out their substance."
"He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures."
"He has plundered our seas, ravaged our coasts, burnt our towns, and destroyed the lives of our people."
Of course, in this case, the complaints were followed by action.
