Yes.
Send your kid to school with a gun and have him talk and pray during class. He will be sent home for disrupting class. You can then file suit. Eventually, after two or three judgements you might make it to the supreme court who will rule that by requiring your child to leave his firearm at home and not talk during class, the teacher and school did not infinge about his constitutional rights.
Anyone else have a different opinion?
I believe you just sidestepped what I was asking you. I was referring to the area in bold, not the gun part.
I think a "vast majority" of parents don't give their children guns to take to school with them, and most kids talk during class at some point.
What if twenty kids are talking during class, all at the same time, but one is praying - are we to send home the one that was praying?
Your case is really falling apart here - I think you'll be fighting with yourself before long. You and your "two buddies", that is.
