The Supreme Court is rebuffing an appeal from a Michigan woman fighting a school district’s ban on shirts with the phrase “Let’s Go Brandon,” a jab at then-President Joe Biden with a coded reference to profanity.
The mother of two boys says their First Amendment rights were violated when they were told to take off the sweatshirts she bought them for Christmas in 2022.
A lower court disagreed, finding that the veiled vulgarity of the phrase, which functions as a stand-in for “F-— Joe Biden,” allows schools to ban it.
The woman’s attorneys argued that the decision wrongly gives school officials wide latitude to squelch political speech based on their personal ideas of what is vulgar. The phrase itself doesn’t contain any swear words or sexual implications, they said.
The school district urged the justices to reject the case, arguing that messages with lewd implications have no place in school, even if they touch on political topics. There has been evidence that some students wore clothing that read “Make America Great Again” or had messages supporting President Donald Trump, a Republican who lost the 2020 election to Biden, a Democrat.


New Jersey v. T.L.O. (1985).
The supreme Court ruled kids 4th amendment right to require a warrant was not eligible to be upheld in public schools.
So when a student steps onto the property of a public school that right is suspended until they leave.
As for being able to detain a student they absolutely can within reason. The courts have decided that the rights of a parent extend to the schools to detain a child do to the fact that the parents are not there.
Thus the “right” to go where you want does not truly exist for a minor whether they are on/off a public schools ground.
Kids have “rights” just not the same rights as an adult.
You have cited a court case which addresses one specifically held legal right, but that does not translate into the broad acquiescence of all legal rights as your argument suggests.
You are wrong.
