A high school sports conference has banned fans from chanting 'USA' during games because it was being used along with Donald Trump signs to 'racially' insult players.

The OK (Ottawa-Kent) Conference in western Michigan announced it has told fans they were no longer allowed to use the chant that at first glance appeared to be patriotic on Thursday.

Commissioner Jim Haskins made the decision and sent an email to all 48 competing schools in the conference, according to MLive.

However, Haskins is not trying to stop people from being patriotic by banning the famous chant, but is instead stopping abusing fans from hiding behind it.

'Fans can chant USA before the National Anthem or after it,' Haskins said.

'But once you start the game, because of the connotations of what people are looking at, whenever you are using it the second time, it can be used as derogatory, such as U Suck (bleep) and those type of things. That's what we have the problems with.

'The OK Conference presidents, the AD presidents and principals have decided to avoid any conflict by eliminating it except for the National Anthem. This is supposed to be used to honor our flag, not to degrade somebody else.'

Parents from the opposing school complained Forest Hills Central students were chanting 'USA' and waving Donald Trump signs and the Betsy Ross flag (pictured) last Friday

The change in policy came after parents made a complaint last week after a game between Ottawa Hills and Forest Hills Central.

Parents of the Ottawa Hills team said the 'USA' chant was being used offensively by Forest Hills Central supporters, who also waved a Trump banner and Betsy Ross flag.

A parent of two students at Ottawa Hills wrote to Forest Hills Public Schools about the incident, which he described as being racially motivated.

'Attached is a photo I took of your four boys. They spent the entire game brandishing a "Trump for President" flag, along with a "Betsy Ross" flag - the flag of the original 13 colonies with 13 stars in a circle, costumed in other flags, running up and down the sidelines,' Matthew Patulski of Grand Rapids wrote on Facebook.

The father of two students Ottawa Hills said the opponents from Forest Hill - a 'predominantly white' school - used the symbols and chants to insult the 'predominantly black' team

'They were also out in front front a predominantly white pep squad of maybe 100 students.

'Our group of parents consisting of various economic and ethnic backgrounds were there supporting our students in marching band while cheering on the predominately black Ottawa Hills football.

'We were all quite taken a back by these loud chants. The circumstance was made even more unsettling by these four boys brandishing these symbols of nationalism and white supremacy.'

Patulski then described the Trump sign as offensive, saying the Republican nominee is: 'known for his tacit support of racist ideologies that is causing a great deal of concern in minority communities'.

The concerned father then turned his attention to the Betsy Flag, describing it as 'a piece of history co-opted by white supremacists who see it as a symbol of a time in our nation's history when slavery was legal'.

He closed the letter by writing a mother, who moved to the area from Chile and has a son of the team, was distressed after the game and asked him to say something.

Despite the passionate letter from a concerned parent and the conference explaining its decision clearly, some upset fans flooded its Facebook page with negative comments.

'Seriously what is wrong with you people if you hate the U.S. why are you here? I am offended byyour (sic) hatred for our country,' Louis Madrid said.

'You people are a joke,' Damien Allen wrote.

'If USA bothers you then perhaps you need to re-think where you live,' Scott Saman said on Facebook.

'Congratulations!!! you are officially a laughing stock!!!' Robin Drake added.

But another Grand Rapids resident praised the change, saying it was 'obvious' what students were doing with the chant, Trump signs and flags.

'You can't deny the overt, intentional racism and intimidation,' Briana Urena-Ravelo told WOOD8.
