The asininity behind it stems from the same mentality that gave us "zero tolerance" policies in schools. It's absurdism that even Python can't grasp. I know someone whose 8th grade son was arrested, yes arrested, for using a pen and rubber band to assemble a spitball shooter in class. Not given detention or something like that, no, arrested by the police at the insistence of the school "administration".
The ability to discriminate, as in intellectually discriminate between different concepts and their contexts, is one of the fundamental components of Reason. That's also precisely why it is forbidden in the soft tyranny of PC America, because it necessarily defers to individual judgment and initiative, and State Almighty has claimed that monopoly for itself. So the result is we have schoolkids shooting spitballs being treated exactly the same as if they had produced a real firearm, and we have toddlers and handicapped grandmothers being treated like 25 year old Arab men with no luggage and one way last minute tickets at airport security.
And it won't stop until we make it stop.
