Okay, but the potential harm / average good of internet access is orders of magnitude away from that of a firearm.

As a teenager, I would have loathed being restricted from the internet the way the above poster describes restricting their autistic teenager's.

(in fact, on one occasion my mother did restrict my computer access because I wouldn't go to the guitar lessons she paid for me anymore, I did absolutely loathe it, and I still consider that mildly abusive)
