Sensitivity to them is what's causing this current push back (and emboldening them). I'm not defending them as some of them go way out of line, but I feel like language policing is a large step in the wrong direction.
Yes, they have. But ordinary people have not. And I believe this is the biggest problem. The trolls have been setting the tone of a Internet that most people don't want.
I want a Internet without harassment and harsh/trololol comments. We need to fight back against the trolls.
My daughter wrote a paper about Gamergate and the crap around that, and she was afraid to publish it widely for fear of retaliation. A bandmate wrote a fantastic song about trolls hating on women in gaming, and we only play it live because she's afraid of what will happen if we release a recording. It's scary. Women are justifiably afraid of what will happen to them if they publicly criticize the trolls.
"Trolling" means different things to different people(just as what people find offensive), and legislating that is dangerous IMO.
