A lot of this is based on his character Captain John Grimes, who welcomes people into his home with:
Come In. This is Liberty Hall; you can spit on the mat and call the cat a bastard!
Now, while this is laid back and relaxed, is it really a statement of liberty? Is spitting on someone’s mat a statement of freedom, or of contempt?
Why be rude about their cat?
Isn’t this an invitation to licence, rather than liberty?
