Nope.  See my argument about Moral Superiority above.  You have Moral Superiority right up until the time you start fighting.

You see, this isn't WWII fighting Nazis, or the Civil War fighting slave-owners.  This is two equally constitutionally protected different opinions assembling in public peacefully.  THAT is your right.

Once you start using violence to express your "right" it is YOU who are the criminal.
