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...

Too true Barbara.

I put forward my view, further down in this thread, on the basis that these persons showed no manners whatsoever in making their objections known - they approached the organiser whilst the concert was underway, thus spoiling his enjoyment and, most likely, that of the people nearest to him. Now, I consider that to be a totally selfish and ignorant act and, for that reason, would make it clear that they were no longer welcome in my home.
