I differ. I'm well aware that it's impossible to really block anything on the internet, just as it's impossible to really block any kind of speech in the real world. But we can try and curb the worst excesses - threats of death and violence - in the "public" spaces of the internet, that is twitter, facebook and so on. It's not only a way to make those spaces feel safer for those who are less privileged than us, it's also a statement from us, as the society that certain behavior is not accepted - because in the end, that's all a law is: A statement that we don't accept or condone murder, theft or other behavior and we, as the society will hand out punishment. And if you think about it - we punish putting bullets into people until they're maimed or dead - why should we not punish putting words into people until they're maimed or dead.
