This article cited here discusses how the left are now so far Left that if the earth was flat, they would be in danger of falling off the planet. Certainly, the Left today are more extreme than Karl Marx:

“In the past five years, white liberals have moved so far to the left on questions of race and racism that they are now, on these issues, to the left of even the typical black voter. This change amounts to a “Great Awokening” — comparable in some ways to the enormous religious foment in the white North in the years before the American Civil War. It began roughly with the 2014 protests in Ferguson, Missouri, when activists took advantage of ubiquitous digital video and routine use of social media to expose a national audience in a visceral way to what otherwise might have been a routine local news story. “If there had been no Twitter or Facebook,” Columbia University’s John McWhorter, an early and somewhat skeptical observer of the Awokening, tells me, “Trayvon [Martin] and Mike Brown would have had about as much impact on white thought as, say, Amadou Diallo did.” Pollsters began to see a rapid, sustained change. White Democrats suddenly started expressing dramatically higher levels of concern about racial inequality and discrimination, while showing greater enthusiasm for racial diversity and immigration. (While political disputes around race are often found under the same umbrella as gender and sexual orientation, where attitudes are also shifting, the relatively recent, relatively sudden change that constitutes the Great Awokening is fundamentally about race and its relationship to national identity.)
