The judge, Gregory Presnell, was acting on a request by the restaurant chain Hamburger Mary’s, which sued Florida last month claiming that the law was overly broad and put a chilling effect on the right to free speech under the First Amendment.
Presnell, an appointee of former President Bill Clinton, determined that while some people may find a drag performer reading a children’s book to a minor during a performance to be inappropriate, it doesn’t necessarily constitute an obscene performance. He also stated that current obscenity laws already “provide Defendant with the necessary authority to protect children from any constitutionally unprotected obscene exhibitions or shows.”
So... No.
