What is childish to you or me may not be to someone else. Yes, I think a curfew is childish, but so is, for example, not allowing people under 21 to drink alcohol, is America a big day-care?

All institutions have rules, the author seems to fake a misunderstanding of what was meant by "day care" in the original post, that is "protect students' feelings at all cost". This has nothing to do with the rules in the institution.
