Barack Obama has done it. So have Oprah Winfrey, Ronald Reagan, Malcolm of "Malcolm in the Middle" and Beyoncé.
But flashing the OK hand signal, in which the thumb and index fingers form a circle, has proved hazardous in recent weeks, with the Chicago Cubs banning a fan for making the gesture behind a black TV reporter, and Oak Park River Forest High School announcing it would reprint more than 1,700 yearbooks at a cost of almost $54,000 because some students were displaying the hand sign. A second local high school, Chicago's Walter Payton College Prep, will also be reprinting its yearbook due to photographs of students making the OK sign.
What happened to the OK sign's reputation for squeaky-clean sincerity? And how should the average person respond?
The short answer is that, starting in 2017, members of a discussion board called 4chan mounted one in a series of attempts to "troll" — or mock — liberals with a right-wing hoax, claiming that the OK sign was a symbol of white supremacy, according to Mark Pitcavage, a senior research fellow at the Anti-Defamation League. The idea was that "the libs" would take up the cry that the OK symbol was racist and, in so doing, make themselves look ridiculous.
Some news outlets took the bait, and the claim was repeated on social media, Pitcavage said. Soon more right-wing trolls joined the campaign, which was anti-liberal but not necessarily white supremacist. Then some actual white supremacists took up the OK sign, apparently still largely as a way to make fun of liberals. And finally, some white supremacists started using the sign without apparent irony, most famously the New Zealand mosque shooter, a self-described racist who killed 51 Muslim worshipers March 15.
All of which leaves the OK sign at a complicated juncture, Pitcavage said.
"I think people should be careful about when and where they decide to make that symbol, because they could be accused of doing it for white supremacist purposes," he said.
At the same time, the vast majority of Americans are using the OK sign in the traditional nonracist ways, he said. That includes the "circle game," a popular pastime among kids and teens in which an upside-down OK sign is displayed below the waist. If your friend looks at your OK sign, you get to punch him.
