First, are you sure the students weren't playing with the "rights to bare arms" analogy? I don't know any of my kids friends that would be serious about that, but a lot of them would think it was a funny twist.
It is possible they were messing around but my friends daughter thought they were serious and she knows the kids. This post has generated quite a bit of dialog about teachers, I know they have a tough job, my dad was a teacher. He took early retirement when Bangeter offered it because he was tired of fighting apathy and administrators that were forcing him to change his very good programs. He taught wood shop, metal shop, and small engine repair and they were forcing him to replace it with the TLC program. My kids did the TLC program and it was a waste of time. My dad tried to get his replacement spun up so he knew more but he wouldn't spend any of his time to do it. My dad would always stay after school to help the kids but after he left the program fell apart. With my own kids I felt like they had too many days off and never had enough homework. Quite often I had to tutor them especially in math and they would often ask why is this stuff important ? Usually all I to do was show them a paractical application and they would work harder at it. I agree completely with everyone who has said that the parents are key to their kids success.
