I'm guessing your reply ends with sarcasm, right?  My point wasn't that violence is the right thing to do.  I'm totally against it.  But, I'm not everyone, either.  Point is, people are different, and and some will react with violence to certain groups.  Sure, protest peacefully, but there's no guarantee you'll be safe doing it.  

And, I wonder how the violence actually started.  My bet is the nazis were a part of inciting the violence...beyond just protesting.
