I want to respond to your post again, with another thought. The "thought process" here, is discernment. To be able to see differences in events. It's the refusal to see differences in events that has caused schools to adopt "zero tolerance" policies, and punish the kids who bring a butter knife to school in their lunches and kids who bring switchblades in their backpacks the same. To punish the kid who offers his asthma inhaler to a friend who is gasping for air the same as a student who passes around hydrocodone. I think it's because people who violate the rules are bent on pointing to others who didn't have the same intent, and demand that everyone be treated equally, and take reason and discernment out of the equation.
These two incidents - the defiant girl, and the peaceful expression of dismay, are two different things and if we allow people to insist they are the same, we've handed in our ability to effectively govern. Those who see the obvious differences should be allowed to run the schools, and those who can't see the differences should put their talents in other directions besides school supervision.
