Public school demands that boy's name be changed because it claims that sign language for name violates their anti-gun policy

From Grand Island, Nebraska:

Three-and-a-half  year old Hunter Spanjer, who is deaf, signs his name by crossing his forefinger and index finger and moving his hand up and down.
To his family, friends and those who know the Signing Exact English (S.E.E.) language that the Grand Island, Neb., boy uses, that gesture uniquely means "Hunter Spanjer."
But to Hunter's school district, it might mean something else. The district claims that it violates a rule that forbids anything in the school that looks like a weapon, reports KOLN-TV.
And Hunter's parents claim that Grand Island Public Schools administrators have asked them to change their son's sign language name.
"Anybody that I have talked to thinks this is absolutely ridiculous," Hunter's grandmother Janet Logue told the TV station. "This is not threatening in any way."
Hunter's father Brian Spanjer said, "It's a symbol. It's an actual sign, a registered sign, through S.E.E." . . .
