It may not be easy in the heat of the moment, but try and change your focus and maybe you can avoid the negative angry energies. Instead of getting mad, try and focus on how stupid this person looks with a mask on and how clueless they are to what is really going on the world. Remember that this a person that will really need you in the future to explain what has happened. You are in the power position. I try to think of it that way....
