As bad as the Nazis are, they have the right to have their march. It's sad that people can't see that and have to start a riot.
Unfortunately, I agree. The way things are these days, you never know if you are the next one to be targeted for your views. The best way to handle it is to allow it. Inciting to violence is different. If Nazis were standing on the croner screaming at their supporters to do something illegal and the actions were carried out, there there would be recourse for action. But the group's philosophy cannot be used to excuse violence against them if they have done no illegal acts.
They know very well that even pedophiles have a right to march. Their intent is to introduce legislation that limits the activities and speech of those with whom they disagree. They urged this looting and violence with precisely the intention of stopping public demonstrations from all but the "chosen few". If I had to bet my dog's life on who is behind this, I would go with the homo-militants.
