Public Elementary School confiscates birthday cupcakes with toy soldiers on them

Can't public school teachers differentiate between a real threat and a toy soldier?  Of course they can.  But the point here is to traumatize kids over anything that involves guns.  Toy soldiers were "insensitive"?  From CBS Detroit:

A 9-year-old boy’s birthday cupcakes sparked a school controversy that just keeps growing, with scores of people lining up against a school principal who found the cupcake’s topping “inappropriate.”
The boy was chided, and so were his parents, for cupcakes featuring little green Army men on the top.
Schall Elementary School principal Susan Wright called the parents at home and said the cupcakes were insensitive in the wake of the Sandy Hook school shooting. School staff pulled off the Army men before they were served. . . .
