From the New York Times:

As the play ended, the actor who played Aaron Burr, Brandon Victor Dixon, acknowledged that Mr. Pence was in the audience, thanked him for attending and added, “We hope you will hear us out.”

I don’t support this – Mike Pence is a paying customer to a see a play, and he should be treated by the establishment as equally as possible. Even if the message is fairly innocuous, I don’t think this was a classy move to do without Mike Pence’s approval. However, with regards to:

When Mr. Pence entered the Richard Rodgers Theater in Manhattan, he was greeted with a mix of clapping and booing, according to theatergoers who posted on Twitter.

While I don’t support this treatment of the vice-president elect, I think this is a fair expression of the theater-goers First Amendment rights – if Mike Pence is free to express his anti-gay beliefs, which he is and he should be, he also must face the public, especially metropolitan, opposition to these views.
