GRAND RAPIDS, Mich. – Some folks who attended a high school football game in Grand Rapids are crying racism after students displayed a Donald Trump banner and Betsy Ross flag during the “red, white and blue” theme night.

“It’s all very obvious. You can’t deny overt, intentional racism and intimidation,” Grand Rapids resident Briana Urena-Ravelo, a Black Lives Matter activist who wasn’t at the game, told WOOD TV. “For these white kids from a white school to bring out a flag of the colonies with the ‘Make America Great Again’ Trump flag to a game with black students on the field, it’s all very obvious.”

Urena-Ravelo is among a host of people complaining about four Forest Hills Central High School students who attended a recent game at Houseman Field against Ottawa Hills High School, which has a predominantly black football team.

The students donned American flags, and unfurled a “Make America Great Again” banner along with a Betsy Ross American flag, which contains 13 stars in a circle to represent the original 13 colonies. Forest Hills students and parents explained that the display was part of the school’s themed football nights, and the Friday game was “red, white, and blue” night, MLive reports.

“There was no ill will intended,” Forest Hills superintendent Dan Behm told the news site. “To the extent anyone felt harassed or intimidated, that was not the intent.

“I think the students feel horrible and I feel horrible,” he said.

Behm noted that when the participating students were notified that their flag display offended Ottawa Hills players and fans, they immediately stashed away the flags.

Regardless, folks were offended, and they’ve taken their frustrations to the media, and posted online.

“What were the conditions for people of color when that flag was created?” Urena-Ravelo said of the Betsy Ross flag, which was first used in the late 1790s. “I was property. Other people were getting their land stolen.”

Grand Rapids parent Matthew Patulski posted an “open letter” to Forest Hills officials on Facebook to air his grievances about the incident.

Patulski wrote:

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. They were also out in front front a predominantly white pep squad of maybe 100 students. Many of these kids were also regaled in combinations of red, white, and blue attire holding regular chants of ‘U-S-A! alternated with a call and response where the first part “Go Green” is shouted by one person and the response “Go White” is shouted by the FHC student crowd.

Sitting in the home stands across Houseman Field, it was a sight to both see and hear. 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 went on to provide links to news stories about alleged racial undertones of Trump’s presidential campaign and the “Patriot movement” using the Betsy Ross flag.

Patulski’s missive, of course, prompted numerous rebukes online.

“These young men have absolutely nothing to apologize for. They were simply showing pride in their country, their school, and some level of interest and involvement in the political process,” Spewncer Helmbrecht wrote. “My guess is that had that Trump sign said Hillary your letter to … would never have been penned. …

“Only when people like you start to see beyond these kids’ ‘whiteness’ will there be any hope of unifying this country. The perceived ‘open display of racism’ exists only in your mind and the other minds you pollute with your own racism.”

“Ahhh gimmie a break!” Jeff Poppen wrote. “Insignificant goofy boys at a football game filled with adrenaline and testosterone. You folks need a life! … Have a cocktail.”

“You have to have lost your marbles to extrapolate that a few kids, displaying political propaganda, during a charged election year equates to racism,” Steve Besser added. “The word racist is being stretched so thin, and thrown around often to end a conversation, that I’m afraid it’s lost its entire meaning.”

Forest Hills superintendent Behm told MLive he plans to respond to Patulski’s open letter, and to speak with seniors about the incident during an upcoming retreat.

Forest Hills won the football game 35 to 14, WOOD TV reports.
