Do you believe the aggressive behavior of Trump encourages an aggressive response?    

 Trump crudely insults those he doesn't like, what would you expect from those who are offended?    If he groped your sister, would you politely ask him to 'please stop'.   If he picked your father as the brunt of a 'cripple' joke and you knew your dad's struggle, would you laugh?

I'm not excusing Hillary supporters of planing any kind of violence.   I am saying hate in contagious.  Trump's bellows fan the flame, but he has no clue how to stop the fire.
