We have religious freedom in this country. Just 20 years ago this would have been laughed out of court. 200 years ago the happy couple would have been burned at the stake.
We still do have religious freedom. No one is binding the inkeepers to Vermont. Admitidly, a small state with questionable laws. Sucks to live in Vermont, but there are many other states with beautiful countrysides where a pure B&B could be located.
It sounds like these inkeepers were just itching to get in the victim spotlight.
