Even by the standards of U.S. politics in the accursed year 2020, the wall of thrusting digital crotches was weird. One day in June, barely a week after a Minneapolis police officer murdered George Floyd and ignited nationwide protests, people started tweeting #WhiteLivesMatter so frequently that it became one of Twitter’s most popular hashtags worldwide. The white supremacist phrase is a call to arms within QAnon, the militant sect that believes God sent President Trump to defeat a shadowy cabal of pedophiles and child traffickers. But the tweets weren’t what they seemed. Anyone who clicked the hashtag or typed it into Twitter’s search bar looking for fellow racists instead found a rolling stream of video clips featuring Korean boy bands, their pelvises gyrating below their smouldering eyes and perfect pastel hair.
