"On Monday, school officials removed Jaiden from class due to his Gadsden flag patch. His mother has fought back against this disciplinary action, explaining that the flag—a coiled snake above the phrase "Don't tread on me"—is not a pro-slavery image; it has its origins in the Revolutionary War and was intended as a symbol of resistance to British tyranny."
