I find it a little ironic that Pence signed into legislation the right for business owners to refuse the LGBT community service based on religious reasons, but he has no problem letting the LGBT community service...uhh, I mean perform for him.
As far as crowd reaction goes, I would like to think I would have taken the high road and not booed, but I can't be sure; and it's understandable for those who did. People, especially the Broadway community and theatre lovers, are sad, hurt, angry, and maybe even scared. It is their right to express how they feel. Pence is the Vice President elect which makes him a public servant. Politicians love to forget that; that they are elected to represent their constituents' ideals, not just their own. And even if ideals differ, every citizen should at least feel safe in their own country. So, the audience and cast had every right to express their concerns and it is his job to listen, whether it is crude or eloquent. And it was perfect timing. The future Vice President is not the most accessible person. It's not like they could schedule a business lunch with him next week, so they seized the moment.
Also, I don't think any Republican would be/has been booed for seeing Hamilton. As much as some people don't want to or fail to realize, this election was not about politics. It wasn't about conservatives versus liberals. It was about love versus hate, about sanity versus insanity, about hope versus fear. And unfortunately hate, insanity, and fear won. So why wouldn't there be a visceral reaction to one of the men that represent that?
