Children do not have First Amendment rights.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Neither do prisons.
Our government schools treat children ( who have committed no crime) like prisoners.
There is a solution:
Complete separation of school and state. Vouchers, tax credits, and charters would assist the transition.
I’m all for vouchers but that won’t give children First Amendment rights.
Or Second Amendment rights.
Or voting rights.
You do your arguemnt disservice by focusing on non existant rights for your issue and comparing children with prisoners.
If those children were in private schools they would probably have fewer priveleges than in public school with no consideration for Constitutional Rights.
