Whether the performance was political or controversial in any way, these two women came to someone's private home, listened only briefly, and then made a scene in the middle of the first set, demanding their money back. I would have firmly told them "No refunds, sorry, you're welcome to leave" and shown them the door. Regardless of their ideology, rude people like that are not welcome. If they had been reasonable and waited until the intermission to discuss their sensitivities with the performers, they might have warranted different treatment, and they might have even garnered some sympathy. Bah, humbug...
