If that’s the case, how far should they be allowed to go with a ban? What happens if they decide that fans of an opposing team shouldn’t be allowed to attend games? Or people who have been oppositional towards ownership or management, like the press. What about banning everyone who works for a vendor or partner because they are sour about a deal going bad or relationship ending? What about politicians or people with opposing views (I don’t believe that’s a protected class?).
Edit: updated to use examples that aren’t part of protected classes.
