As you can see from my message above, I'm not completely against violence.
But if that's the way you conduct your life, I'm afraid you'll soon end up in jail.
If that is not the case then you either never see nazis, which is not so common these days, or you're speaking empty words.
I had those kind of confrontations which end up in people picking up sticks and taking out knives with congregations of neofascists in order to protect the integrity of places, in periods in which those were being targeted and it was quite common to hear someone from your circle of friends had gotten murdered while getting back home.
What are you talking about?
