That is not funny.
First, understand that for nearly 250 years this type of speech would be both unlawful and prosecuted. The First Amendment doesn't allow any type of speech.
The type of speech portrayed here violates several laws... Public Exposure and Obscenity laws, sedition as it is an outward act of rebellion, and finally it violates the Flag Code which prohibits such displays of our flag... in spite of erroneous and malicious supreme court decisions the executive should pursue this matter until some common sense prevails and such acts are prohibited... as unlawful not protected speech.
Immigration does have its politics.
