It was a humorous display of conservative fascism's bravado to think they can tell everyone what do like and do. The news ... MIKE PENCE was angry that the HAMILTON cast criticized him, when he attended their showing, saying they were concerned he would not defend them in their diversity.
This caused Trump to tweet angrily...
"Our wonderful future V.P. Mike Pence was harassed last night at the theater by the cast of Hamilton, cameras blazing.This should not happen" - The Guardian
But...seriously... This was THEATRE. As even the article notes, it is filled with people of color and sexual orientation and ALWAYS has been. Until the last few hundred years, it was common for ALL roles on stage to be played by men...even women roles in full Crossdressing, trans glory on stage for kings.
So...the humorous bravado is that the most recognized racist homophobe going into the liberal theater IN NEW YORK expected anything else. It wasn't like this was a show in a state that actually VOTED for him, and neither Trump or Pence can ORDER people to love the very ones attacking them or pledge to them)...at least not yet.
Theatre is a place of self expression and free speech, and as such it is a place where people can say what they feel and be applauded by those with open minds that appreciate the freedom. May it always remain FREE of GOP fascist control.
