Two mobs? Peaceful protesters don't make a mob. The Nazi/white nationalists were instigating fights with everyone that was against them.  That means there was only one mob and one group terrorizing others.

With regards to the specific acts of single individuals, they are the same. I am talking specifically about the car/truck attacks that are similar.  One guy got out and shouted Allah Akbar to show his idiotic devotion the other sped away.  That doesn't mean that because he sped away he wasn't just as evil and a terrorist.  They both killed innocent people because they disagreed with them.  They are both terrorists.
