Please, be PC; It’s buggerers in the UK.
There is a difference between being sinful and being evil. The two “gentlemen” in question qualify in both categories. Using the law as a club to punish people for following their faith in their own home is something that even George Orwell never considered or perhaps rejected as too far fetched for fiction.
Personally, if these “gentlemen” had shown up at my B&B, and I had been aware of the disgusting shift in national law, I would still have turned them away. But I would have offered a difference reason, one that would have been true and not criminal. I would have told them that we had decided to close the B&B effective immediately and were not accepting any new lodgers but that their deposit, if any, would be cheerfully returned. Then I would actually have closed the place as soon as the remaining lodgers checked out, either permanently or until we re-evaluated the decision. I would not allow either tyrants or perverts to tell me what I must permit or may not permit in my own home.
