No problem with anything you've said. Maybe another solution: Administrators become creative and find a way to effectively separate kids that comply with generally accepted standards of conduct which include respect for others, decency, etc... from those that don't.Kids from the backgrounds of dysfunctional families that bring that dysfunction to school inhibit everyone from learning. FACT. Yes, I want my grandkids to know the difference from buckling down to learn & being a distraction. FACT.
That you don't believe that kids deserve to be in a save space at school & coming/going tells me don't give an ish about kids of any kind. You must love school shootings.
My solution is for parents to be allowed to send kids where they want & not just where the politicians & teachers unions tell them they have to go. That has never failed. As is, the only way to achieve that is to move to where the school is you want the kids in.
Before retiring, we began toying with an idea of forming night schools. We'd simply tell kids and their parents what the accepted standards for behavior were. If their kids chose not to comply, they would go to school from 3:00 until 10:00 pm. It's not our problem how their kids are monitored during the day. Put the ball in their court. Does not matter what their problems were; does not matter what their family problems were. Simply a choice on their part based on how they chose to behave.
