An old saying in showbiz is “there is no such thing as bad publicity.” For every Trump/Pence supporter who might have seen the show but swears off it there will be a bunch of anti-Trumpers, Hillary supporters and otherwise curious people who will make a point of seeing it when it comes in town.
The best thing we can do is let the controversy die. Only mention how rude the individual was if someone else brings the subject up and otherwise let it die.
