Kate Upton was one of many Americans who took exception with the handful of NFL players that decided to kneel during the National Anthem prior to yesterday's full slate of games. 

In response to a tweet sent out by SportsCenter, which showed multiple Miami Dolphins players including Arian Foster kneeling for the Anthem, Upton wrote, "This is unacceptable. You should be proud to be an American. Especially on 9/11 when we should support each other." She added, "Protest&speak ur mind whenever u want but during the 120secs you should support the people who protect our freedom."

Upton hasn't back down from her stance on the issue, nor has Arian Foster who responded to the criticism with a few tweets of his own. 

In addition to the comments she made on twitter, Upton posted a lengthy message on instagram in which she reiterated that players should always stand for our National Anthem, especially on a day like 9/11. 

Other teams like the Seattle Seahawks and Kansas City Chiefs showed their solidarity by standing with their arms locked during the Anthem. Chiefs cornerback Marcus Peters also raised his fist in the air as a show of support for the cause. 

Colin Kaepernick, who has spearheaded this form of protest, and the 49ers didn't play yesterday but they'll be kicking off their season tonight against the LA Rams.

In my opinion, the national anthem is a symbolic song about our country. It represents honoring the many brave men and women who sacrifice and have sacrificed their lives each and every single day to protect our freedom. Sitting or kneeling down during the national anthem is a disgrace to those people who have served and currently serve our country. Sitting down during the national anthem on September 11th is even more horrific. Protest all you want and use social media all you want. However, during the nearly two minutes when that song is playing, I believe everyone should put their hands on their heart and be proud of our country for we are all truly blessed. Recent history has shown that it is a place where anyone no matter what race or gender has the potential to become President of the United States. We live in the most special place in the world and should be thankful. After the song is over, I would encourage everyone to please use the podium they have, stand up for their beliefs, and make America a better place. The rebuilding of battery park and the freedom tower demonstrates that amazing things can be done in this country when we work together towards a common goal. It is a shame how quickly we have forgotten this as a society. Today we are more divided then ever before. I could never imagine multiple people sitting down during the national anthem on the September 11th anniversary. The lessons of 911 should teach us that if we come together, the world can be a better and more peaceful place #neverforget.
