Why not Ban travelling to Manhattan.
How about banning riding the Subway.
How about banning visiting such stores as Macy’s
I’m unsure what you are trying to say. It sounds like your argument is, that if schools are going to legislate morality on their students, then they should intrude into every aspect of their lives.
That sounds bizarre. I’m not sure why you would criticize the schools for being responsible and not intruding into every aspect of the students lives.
Unless you are saying that you think going to Macy’s is egregious enough that it is similar to facebook. That is a strange opinion.
