Free speech for some, but not for others: That’s what a school district in Minnesota is accused of engaging in after it silenced a conservative group upset over anthem protests.

Now, the district is facing a federal lawsuit from members of the Young Conservatives Club.

The controversy started in November, when a group of liberal students at Edina Public School near Minneapolis protested during both the national anthem and a “taps” ceremony meant to honor soldiers on Veterans Day.

According to USA Today, the conservative student group posted a video speaking out against the protest, objecting to the behavior of several left-leaning young people who had refused to stand to honor veterans.

Several other students who were not members of the conservative club made disparaging comments on the video.

A different video posted by anonymous students calling themselves Edina High School Anti-Fascists (antifa) also referenced the Young Conservatives Club, and threatened members of the conservative group.

In response to all of this, the school completely disbanded the Young Conservatives Club.

“Edina High School has essentially declared itself to be ‘Big Brother’ — to ensure that students ‘think correctly’ about the U.S. flag, political and social issues,” Erick Kaardal, an attorney representing the conservative students, told USA Today.

Edina High School Principal Andrew Beaton allegedly told club president Nick Spades that even posting the video of other students protesting the American flag and veterans was a violation of school policies.
