None of this is the slightest bit responsive to the point I made that some people;s response to losing an argument is to engage in violence. There's no law to enforce here, nobody suggested that Lane Davis should be arrested for the holding Nazi opinions. It's a simple observation that the solution to bad speech is not always more speech because people who are engaging in bad speech in bad faith often aren't interested in making progress through dialog.

That's why online trolls often make arguments that are empty of meaning but cling to a posture of superiority - they are not interested in winning an objective argument, but in having the appearance of controlling the conversation, so that if the honest interlocutor gets exasperated by the trollish arguments, the troll claims victory. Provocateurs at real life demonstrations engage in the same tactics. Supporters of authoritarian rulers revel in the discomfiture of their political opponents rather than any objective improvement in their own conditions.

Now, if you want to make general policy points and articulate your views that's fine, but if you're going to simply ignore your conversation partners and beat down straw man arguments of your own creation, why should anyone take your nostrums seriously?
