I paused this video at 1:52 in an attempt to answer this question. A Progressive would say that the government needs to protect the rights of a minority, a conservative would defend the religious beliefs of the business owner and a Libertarian would say let the market decide. This of course means that if you choose not to serve them then you risk losing business, of course why would a gays go back to that business when it was forced to serve them by the government and the same goes for the progressives who would boycott a business that refused to serve because of religious freedoms. So really your fucked anyway you look at it, there best choice is to keep their mouths shut about why they are refusing the business.
