I just came across a post that @renatalemorais had linked to. You can find it here and I really think you should take the time to look at it. It is called Trouble at the Koolaid Point.
Internet harrassment is not just an abstract issue about "rights", and its consequences are not merely statistical. There are serious issues about politics and the kind of world we want to live in buried here, but not very far from the surface. We should bring them fully to the surface and resist any attempts to bury them again.
