At the @UWBadgers game and there is a man with a mask of President Obama and a noose. This is racism, why was this allowed into the stadium? pic.twitter.com/zKEqhdDYny

Talk about going out of bounds. A pair of football fans showed up to a University of Wisconsin game Saturday with a Barack Obama mask ― and a noose wrapped around its neck.

The person in the Obama mask wore a black and white jailhouse suit. (They later swapped the mask of the president for one of Hillary Clinton mask.) Their companion wore a mask of Donald Trump.

A bystander tweeted a photo of the offensive costume with the words “This is racism, why was this allowed into the stadium?”

According to the university, the fan carrying the noose was asked “to remove the offensive parts” of the costume after it was reported to guest services. But because the fans were exercising their right to free speech, they were not asked to leave.

“The costume, while repugnant and counter to the values of the university and Athletic Department, was an exercise of the individual’s right to free speech,” the university said in a statement.

The out-of-touch characters were later filmed appearing to exit the stands wearing Trump and Clinton masks.

Many on Twitter were outraged, calling the display a form of hate speech.

@UWMadisonPolice So Hate Speech is allowed on your campus? The blowback you are getting on this is so deserved. — Cheryl pochapin (@6puma) October 30, 2016

@UWMadison @UWBadgers Lynching costume of this country's first AA pres, it's not free speech. It's hate speech. Go read a history book. — Laura Davis (@lcdavis1) October 30, 2016

@UWMadison @UWBadgers I am supremely disappointed. As an alumnus, I expect an apology for lack of ejection and a promise to eject next time. — Brad Grzesiak (@listrophy) October 30, 2016

@UWMadison @UWBadgers pretending to hang a black person is not free speech — SlimTem (@temitayo_coker) October 30, 2016

Twitter user @woahohkatie, who appeared to be the first to post the photo, later wrote that she and a friend since received “hate tweets” for standing up against the obscene display. Some of the tweets, she wrote, included “people encouraging us to kill ourselves.”

“The internet is a wild and violent place,” she concluded.
