And if we were talking about people talking shit on private property your point might be relevant. Alas, we're discussing things going on in schools, on the internet, and on the streets in crandc's example.
Are we talking about public spaces? I'm not sure about that.
The internet (much of it) is private property, as are schools and some roads.
You seem to be on an anti-censorship kick and while that might be tangentially related to the topic it isn't moving us forward (fo'ward).
Bullying teaches people essential life skills. Also hearing disgusting opinions is part of life as well.
It teaches people how to socialize and get integrated with society.
I think you're approaching this question from a statist perspective. I do not want to make public areas more "efficient" or create more laws to stop bullying. I want private areas that regulate bullying, or allow it to occur.
More to your point of bullying building character, if that's what you're getting at--I'm not certain--I'm not sure that's relevant either since we're talking about Amanda Todd who is dead.
Her response was not normal imo, and the man in question is a creep for wanting to see her get naked. Aside from that what is your point? If someone has mental issues I see that as their problem (if of adult age), or their parent's problem.
That doesn't mean I wouldn't try to donate to Amanda Todd's family, etc., it just means people have the right to say horrible things even on the internet.
I don't know if it is a criminal case but I think we can agree that there is a point where harassment can go far beyond what you called unsavory language and criticism and ventures into stalking and torture.
I'm not sure what your point is about the internet, you don't own this website for example. If Denny allowed it I don't see why someone shouldn't be able to say the worst things about you.
Now he has made this website in a way that restricts that level of bullying, and good for him. He has no obligation to do this though.
