They weren't just chasing him, they were throwing snowballs at him, and if you don't care about that then I don't care about some stupid POS thug protestor who was harassing people at a rally he was not invited to and then got some weak little punch from a 78yr old man. Cry me a river.
But that is all moot at any rate, it just further illustrates your double standards. Dwelling on one incident involving a 78yr old coot who probably couldn't win a fight with Mr. Burns and you blame it on Trump and all his supporters, yet when Rand's supporters curb stomp someone is that your fault? Is it Rand's? Oh no, suddenly we go back to blaming the individual for their actions and not the entire group.
