Lol. There is nothing inherently antisemitic about this meme. The whole "nazi frogs" and "nazi clowns" hysteria exists because those memes originated on 4chan and because 4chan is rather visited by various types of right wingers, they simply started using this meme before the left. Memes have some ideas or emotions attached to them, but they are not inherently political, sad Pepe represents depression and being a looser, smug Pepe represents trolling or optimism, the doomer represents being part of modern "lost generation" and the Honkler represents the idea that the world is a joke. The concept of clown world is quite nihilistic and contrarian one. The early versions of the meme had nothing to do with politics, yes some peope used it to mock jews or black people but as I said memes are not inherently political, the same was with NPC meme, it originally represented people without their own opinions. Even ADL claimed that Pepe is not inherently anti semitic, it is all about context.
