Who would be the objective judge and decide what kind of speech is violence?

I found dhh's comments about the London march misguided. Describing the symbol of BNP/EDL as heartwarming is particularly upsetting. It puts me off Rails, and attending conferences where he is the keynote speaker.

> Verbal violence can be just as hurtful as physical violence - calling someone a Nazi, a facist, a loony, stupid, retarded, and even worse is violent.

If calling someone a Nazi or a fascist is violence, I guess I'm a violent man at heart.
