I guess we need to talk about Pepe the Frog

Et tu, Pepe?

Pepe the Frog -- a multivalent green cartoon used in Internet culture as a vehicle for a wide range of emotions and ideas -- has over recent months become particularly associated with racism, anti-Semitism and the alt-right.

And on Tuesday, the Anti-Defamation League added Pepe to its "Hate on Display" database of symbols used to spread hateful messages.

The anthropomorphic frog, which is based on a 2004 comic by Matt Furie, is frequently shown as smug, sad, angry or rather gross. Like most memes, he's frequently used in variations and remixes. Know Your Meme, a guide to image macros like Pepe, has collected some examples and a short historical summary.

By late 2014, the meme had spread from a handful of Internet communities into mainstream culture, much to the displeasure of groups that were originally using the image. Later, observers began noticing an increase in white supremacist themes in Pepe images -- or a rise in Pepe usage by white supremacist accounts. Either way, an association was building.

This May, an "anonymous white nationalist" told The Daily Beast that the shift was intentional: a dedicated campaign to "reclaim Pepe from normies," or members of the mainstream, by making Pepe so culturally unacceptable that only the fringe Internet would dare to use him.

Donald Trump had earlier tweeted an image of Pepe-as-Trump, and then his son posted an image on Instagram that included Pepe. This month Hillary Clinton's campaign released a widely mocked "explainer" that featured both those posts and called Pepe the Frog "a symbol associated with white supremacy." Now, the ADL has stepped up to label the frog a hate symbol.

ADL's inclusion of Pepe in its database does not, as some online have suggested, mean that using Pepe memes is a hate crime. It's a designation that carries no legal weight, and the ADL is quick to note that the mere use of Pepe the Frog doesn't, by itself, indicate extremism or hatred.

Furie, the artist who drew the original frog, told The Atlantic he thinks the association with far-right ideology is "just a phase."

"In terms of meme culture, it's people reappropriating things for their own agenda. That's just a product of the internet," he said.

With that, let's pause here to note a few things.

First, if the entire concept of the Pepe the Frog meme makes no sense to you, don't try too hard to crack open the enigma.

Life is short, much of Internet communication is more Dada-esque than denotative, and mastering dank memes has an effort-to-payoff ratio that really, truly is not worth it. Suffice to say he's a character used to express things online, through endless variations on a simple image.

Second, Pepe the frog is not usually racist. There's nothing inherently hateful about the original image: "He's just a chill frog," as Furie told the Atlantic.

And as ADL acknowledges in its hate symbol database, "the majority of uses of Pepe the Frog have been, and continue to be, non-bigoted."
