The parents complaining are the outliers.
Or they will make the parents seem like outliers. Look up the Delphi Technique. It’s almost a form of gaslighting. If an individual parent complains, the parent would be told that he is the only person to hold that objection, even if there are more. In this case the parents in attendance of the board meeting will be told that they are the only ones objecting, or that they are astroturfing, being paid to push an outside agenda (well, that’s projection as well).
These boards are deliberately lying.
