“I think it’s inappropriate”
Great, dont send your daughters to this school.
Those who do, either feel it is appropriate, or dont feel it is enough of an issue to make a big deal out of it.
Any parent who thinks it is inappropriate and continues to send their daughter to this school is a fool and if they speak out against it undermines their daughters chinuch (how much respect would you have for your own teachers if your parents badmouthed their decisions).
