Doxing is surely the supreme act of internet violence. I think this is what journalists don't understand. Anonymity on the internet is what gives one the absolute autonomy we all find so liberating. To unilaterally take that away from someone is probably the most aggressive and violent thing you can do while still remaining in the virtual world.
That doesn't necessarily mean it's always wrong for a journalist to do that, but it should give insight as to why people are so upset here.
