Apparently, the organization of the tournament has violated Florida State Law, which regulates that casino employees cannot prevent men from participating only in events for women. Man's participation was within the law, which is greater than the tournament rule. This is a fact!
However, for those who believe, of course, there is a biblical passage of St. Paul that says "everything is lawful but not everything is convenient for me" (1 Corinthians 6:12). Without wanting to be moralistic, man's attitude may not have been right, but he was not wrong either. Complicated that.
