The alt-right uses memes as an online radicalization tool. One of the best-known icons is Pepe the Frog, a meme co-opted by 4chan in 2008. Honkler resembles Pepe, but in a clown outfit. While Pepe has innocent uses, Honkler has explicit racist connotations and is alt-right, often used by neo-Nazis.
"Clown world" was a phrase used in the subculture from about 2015. Its users claim it simply means that the (Western) world is so "crazy" in its embrace of social justice politics (read: not racist) that the only people who could conceivably be running it are Jews clowns, hence "clown world". More plainly, this is a reaction to social change, showing disappointment that the real world doesn't work like Leave It to Beaver. In reality, countries without closed borders and which don't allow for the ethnic cleansing or genocide of minorities are "clown countries" because they don't embrace the policies of the Third Reich. The phrase started being heavily promoted on The Right Stuff's podcast "The Daily Shoah" in 2017.[3]
