My thoughts exactly. The school principal at first was cooperative, then he and the headmaster turned on Courrielche, demanding silence and threatening to kick his kid out of school.

Obviously someone scarier than Mr. Creepy was threatening all the players involved here but, interestingly, not threatening Courrielche directly (unless he was threatened directly but isn't saying so).

Our school principal said they’d avoid calling social services, but advised us fathers to confront Mr. Creepy.

...then later...

The school headmaster, who’d earlier supported our position, now summoned us to his office and claimed parents were more disturbed about us than the Creepies’ behavior. He demanded we keep quiet. The Creepies hadn’t broken any laws, he claimed. When we requested that he mediate between us and The Creepies, he declined. When we asked for a change to the school’s code of conduct making a parent getting in bed with someone else’s kid an expulsion offense – as was using the n-word off campus – the school would not comply. Weirdly, after the principal advised us not to call social services, the headmaster now wondered if we were so concerned, why then hadn’t we called social services? We’d already made that call. He eventually threatened to expel our daughter if we didn’t stop talking about it – an act that would have surely blocked us from admission into other private schools in the area. The school’s priority should have been protecting children. Instead, it appeared more important to them to protect the Hollywood elites.
