This really shouldn't be a big thing to people. If Nintendo had called it the "Wii Assault Rifle Attatchment" or something to that effect, I could see how people would get angry, but the "Wii Zapper" just sounds too cutesy too be a big deal. (I'm posting on the internet channel on the Wii, so I can't quote, but) a previous poster said something along the lines of, "I play shooters and I enjoy paintball, but I've never wanted to shoot someone." I too am like this, as are many, so I hardly think the Wii Zapper could make kids want to shoot people.
Now my wrists are dust from all that typing, lol
