It took me a while to actually understand. The reason is that hardly any articles lay it out that way. Also the term ‘public bathroom’ and ‘publically owned bathroom’ seem to be used interchangeably. Maybe what the NC law should have done was allow Charlotte to let men use their publically owned exclusive areas if they want, but give the right choose back to private business. I don’t know.

I don’t think the state legislature could pass a law making a general rule, but excepting the City of Charlotte. On the other hand, if the original Charlotte law had applied only to city-owned property, the state probably wouldn’t have gotten involved.
