I'm not so sure. The weird thing about "Gunsmoke" was that it featured a saloon whorehouse run by Miss Kitty. I was always amused by how matter of fact that Marshall Dillon and the other characters were about that.
I’d say it was “conservative” in a libertarian sort of way.
Wrong. Saloon girls weren't generally whores. They sat and talked or danced with the customers, and kept them drinking. Saloons were in the good part of town. Brothels were usually separate businesses, often separated from the good part of town by the railroad ("on the wrong side of the tracks").
