ADL Adds “Pepe the Frog” Meme, Used by Anti-Semites and Racists, to Online Hate Symbols Database
Joins Echo, Swastika, and Blood Drop Cross
New York, NY, September 27, 2016 … The Anti-Defamation League (ADL) today identified “Pepe the Frog,” a cartoon character used by haters on social media to suggest racist, anti-Semitic or other bigoted notions, as a hate symbol. It has been added it to ADL’s online “Hate on Display” database.
Also referred to as the “sad frog meme,” Pepe the Frog did not originally have anti-Semitic connotations. But as the meme proliferated in online venues such as 4chan, 8chan and Reddit, a subset of memes came into existence promoting anti-Jewish, bigoted and offensive ideas. And those have spread virally on Twitter, Facebook and elsewhere.
