I say just pull your weapon aim it at them, tell them to scram and then let them know that they should be glad he’s not like them or they would all be dead...
It would be way cool to pull a 44 magnum out, stick it to the punk’s nose and say “This is the most powerful handgun in the world. And if I ever hear of you so much as raise your voice to another human being I will use it to blow your head clean off. Now, wet your pants then get the hell out of here!” Then fire one off into the air.
