So. No specific "code" violation, but it's in violation of "school policy".
These people are lunatics who dislike guns and little boys.
That's it, Pandora. They want to rout out ANY distinctive attributes of little boys (and girls) & create more "it's" who identify as a man today, a woman on Wednesday & a who-knows-what on the weekend. Like religious pluralism, which attempts to pound ALL religions sheet-metal flat...so that there are no apparent distinctive claims & that none can claim "truth" or an upper hand or way.
