What started as a way to troll the media has been so thoroughly adopted that it is now a legitimate hate symbol.

The “OK” hand symbol, of thumb and forefinger placed together and the remaining fingers splayed out, has been officially recognized as a hate symbol by the American-Defamation League (ADL).

While the gesture has long been known as an innocuous sign for approval, and was intentionally seeded through 4chan and used as a way to troll the media into believing it was a common sign among white supremacists, it has become so widely used as a way to signal hate that the ADL determined it qualified for its database of hate symbols.

Brenton Tarrant flashed the symbol (above) while in a New Zealand court to face a murder charge in connection with the Christchurch mosque shootings.

Former Breitbart editor Milo Yiannopoulos, who used the publication to mainstream white nationalist ideas and give further prominence to the so-called “alt-right,” recently took credit for starting the phenomenon of the use of the “OK” symbol to mean white power, noting the hand gesture looks like a “W” and a “P,” during an appearance on the podcast Legion of Skanks.

Additionally, 35 other new symbols have been added to the database. Another addition includes Dylann Roof’s bowl haircut, as the mass shooter, who targeted a predominantly African American church in South Carolina, has become a hero among fellow white supremacists who have adopted his hairstyle as a symbol encouraging similar acts.

Also on the list are the “Happy Merchant,” which depicts a stereotype of a Jewish person, with exaggerated features, rubbing his hands together to symbolize greed, and the “Moon Man,” from a 1980’s era McDonald’s commercial, which white supremacists have used to create videos in which he raps about bigoted themes. The slogan “Diversity = White Genocide” is also on the updated list.

“Even as extremists continue to use symbols that may be years or decades old, they regularly create new symbols, memes and slogans to express their hateful sentiments,” said Jonathan Greenblatt, ADL CEO, in a statement. “We believe law enforcement and the public needs to be fully informed about the meaning of these images, which can serve as a first warning sign to the presence of haters in a community or school.”

“These are the latest calling cards of hate,” said Mark Pitcavage, Senior Fellow in ADL’s Center on Extremism and an expert on hate symbology. “While some hate symbols are short-lived, others take on a life of their own and become tools for online trolling. We pay special attention to those symbols that exhibit staying power as well as those that move from online usage into the real world.”
