LADUE • The Ladue School District posted and then removed on Monday a photo on its Facebook page that included a student making a hand symbol associated with white nationalism.

In the photo, three students and the school mascot, a ram, pose during a pep rally on Nov. 30. Students were celebrating the high school’s trip to the state championship football game the next day, versus rival Mary Institute and St. Louis Country Day School.

On Monday, more than a week after Ladue beat MICDS 48-11 on Dec. 1 to win the Class 4 championship, the school district posted several photos from the rally and a follow-up celebration to its Facebook page.

In one of those photos, a white student in a Ladue sweatshirt held up his right hand in an “OK” symbol, his thumb and forefinger joined in a circle, his three other fingers raised in the air.

That symbol has been used to mean “white power” for a few years — but it has gathered prominence and publicity over the last few months.
