I think this is a something without general and clear-cut answer. I don't think there is something inherently wrong if you run a hotel only for women or people of a specific religion, probably because your offering is tailored to your audience in some way. But if every hotel would start to randomly decided to set up rules who can and can not stay there, I would definitely see this as a case of discrimination. There is tension between your right to run your business the way you like and the right of your potential customers to not be discriminated and there seems not to be a general and easy way to draw the line.

There are easy ways to draw the line. There are also comfortable ways to draw the line. There are precious few that are both. Therein, I submit, lies the tension.
