Its not a smart move to go face to face with someone who has a height and weight advantage.
Looked to me like he was being swarmed by jacked up racist little thugs. They could do and do do damage to the adults when they swarm. I would have hit her if she came at me with fists cocked like a fighter. With all her thugs around, I would not take the chance on getting knocked to the ground. They were surrounding him with aggression and he has no way out but to push them out of the way.
