Many Americans agree that taking a knee during the national anthem is disrespectful. Unfortunately, it’s become a movement in the NFL.

It all started last year when the quarterback for the San Francisco 49ers decided it would be a great way of protesting the alleged social injustice taking shape in the United States.

No longer in the NFL because his talents are lackluster, the Muslim activist and Black Lives Matter supporter took his protests to the next level on Thursday, when he participated in what some have deemed the annual “Unthanksgiving Day” on Alcatraz.

Kaepernick made the surprise appearance at the event that commemorates the nineteen-month occupation of the prison by Native American activists from 1969-1971.

Today, the event is officially known as the Indigenous People’s Sunrise Gathering.

“Our fight is the same fight,” Kaepernick told the crowd, in a message he posted on Twitter. “We’re all fighting for our justice, for our freedom. And realizing that we are all in this fight together makes us all the more powerful.”

The 89 activists who occupied the prison demanded that it be turned into an American Indian cultural center and school, according to reports.

Newsweek reported that the event includes traditional dancers and the crowd gathers together to watch the sunrise on San Francisco Bay.

Kaepernick, who was recently named GQ’s ‘Citizen of the Year,’ also tweeted a video of the event. He wrote:

“Today, I was on Alcatraz Island at the Indigenous People’s Sunrise Gathering, in solidarity with those celebrating their culture and paying respects to those that participated in the 19 month occupation of Alcatraz in an effort to force America to honor the Treaty of Fort Laramie.
