student asked to change how he signs his name

I read the post about the 3 year old student who is deaf and has been asked to change the way he signs his name because his signing resembles a gun. I personally think this is a little ridiculous. First off, the boy is only 3 years old and has been taught to sign this way and has never been condemned for it before now, so this has to be confusing to him. Second, I feel like with the age that he is at this shouldn't even have to be any sort of problem now and if he is surrounded by the same kids throughout school it'll never be an issue. Him signing won't resemble a gun to his peers, they'll see that symbol and think his name before they'd think it was a gun.
