Re: Slippery slope.. @Norfolk
Firstly, it's not only children who harass; in this case, it was done by an adult.
Secondly, it's not only children who are subject to persecution. Gays, blacks, Asians, physically handicapped... the list goes on.
You're clearly being facetious in your second paragraph; it looks like you don't have either the experience or empathy to understand just how vicious people can be and what it can result in.
Think about it: if someone you knew was subject to abuse all day, everyday, would you be happy to do nothing and have nothing done about it? No matter what the consequences?
