You might suggest to your son that even if his friends do not in fact hunt, they might enjoy seeing his pictures of his deer. They may not be able to hunt because they don't know where to hunt, their parents are not themselves hunters, their parents don't have time to take them hunting. Just have him take his photos in . . . and show them to the boys. Even if they don't hunt, boys aren't likely, I think, to have strong negative reactions to hunting. Girls, on the otherhand, could be a different story. They might look on it as killing Bambi or Bambi's mom.
