A middle school student is speaking out after he was ordered by educators to remove a t-shirt that said, “There are only two genders.”

As reported by Fox News, “Liam Morrison was expecting a comment or two from his peers when he wore a t-shirt to Nichols Middle School” in March. But while his student peers supported him, the school claims otherwise.

“Everyone in my homeroom and everyone in my gym class had supported what I had done,” Morrison told Fox News Digital. He went on to say that no one got angry about the shirt or directly confronted him over it.

However, on March 21, he was pulled out of his gym class and instructed to take off the shirt because several students and staff members allegedly had complained about it. After he said he respectfully declined to remove the shirt, school officials called his father and asked him to come and pick him up.

According to an email obtained by Fox News Digital, Middleborough Public Schools Superintendent Carolyn Lyons claimed that Morrison had violated the school’s dress code by wearing the shirt. She stated that the “content of Liam’s shirt targeted students of a protected class, specifically in the area of gender identity.”

Morrison said he wore the shirt because he believes in the First Amendment’s right to free speech and expression.

“The reason that I wore it is because, well, everyone has a right to their opinions and I want to be able to voice mine on a subject that a lot of people were talking about,” he explained. “I definitely don’t like that they violated what is basically the first thing that the people who were in charge of America at the time stated we were allowed to do and nowadays it feels like that’s being taken away a lot, which is why some people choose to speak up about it. It’s not just me.”

On Monday, the Massachusetts Family Institute (MFI), a non-partisan public policy organization, sent a demand letter to NMS stating that the school had violated Morrison’s First Amendment rights, Fox News noted. According to Sam Whiting, one of the lawyers representing the Morrison family and a staff attorney for the MFI, the school’s actions constitute a “pretty plain case of censorship.”

“There’s case law dating all the way back to the 1960s and maybe even before that states very clearly from the Supreme Court that students don’t lose their right to free speech when they walk in the schoolhouse door. And that’s exactly what the school was trying to do here,” Whiting told the network.

“You know, Liam was trying to express his opinion on a topic that is controversial in our culture right now. It’s a political topic. A lot of people have different opinions on it. But they said that opinion, you know, is not authorized in school and so you’re not allowed to state it,” he added.

He went on to say that unless a student is causing a “material and substantial disruption in school” or they’re trying to advocate for an illegal activity like drug use, then students have the “right to express their political opinions- to express their beliefs on things like this.”

“And so, you know, here they’re trying to say that some students complained or were upset about Liam’s shirt. But the law is clear that other students being upset about something that you say doesn’t even come close to causing that kind of substantial disruption that would justify them clamping down on your free speech rights,” Whiting added.

The student said if someone had confronted him over the shirt’s message, he would have simply said, “They are entitled to their opinions just as I am.”

“If you have a different view and if they asked why I was wearing it, I’d say because I have a right to have a voice,” he explained.

He said he plans on wearing the shirt again on Friday and that he’s “ready” for what may come.

That said, Stoneman, Chandler & Miller LLP, the law firm representing the school, informed MFI and Morrison’s family Thursday afternoon that officials will continue to “prohibit the wearing of a t-shirt by Liam Morrison or anyone else which is likely to be considered discriminatory, harassing and/or bullying to others including those who are gender nonconforming by suggesting that their sexual orientation, gender identity or expression does not exist or is invalid.”
