The Supreme Court has rejected an appeal from a Massachusetts student, Liam Morrison, who was prohibited from wearing a T-shirt stating 'There are only two genders.' The court upheld a lower court's ruling that the shirt could disrupt the educational environment, particularly for transgender and gender-nonconforming students. Justices Alito and Thomas dissented, arguing that the case raises significant First Amendment concerns regarding student speech. The ruling aligns with previous decisions allowing schools to regulate speech that may demean others or disrupt learning.
