To an extent, I do agree, however it’s not the whacky ideas that the youth are coming up with for themselves that’s the problem. e.g. in the 60s the whacky ideas were bubbling up in opposition to a more staid, establishment university system. Nowadays, the whacky ideas are entrenched in the Univerities themselves, and whatever opposition is against the University establishment, it’s more in the nature of purging the old guard for not being whacky enough.
There’s a long history to this. It starts with Lenin’s essay on “Imperialism” as a response to the predictive failure of Communist doctrine at the turn of the century, and Gramsci’s farsighted musings in the 1920s. It continues with the split of the Left during the 30s and 40s into the three major factions of Communism (the old internationalist socialism), Fascism (nationalist socialism, socialism in one country, a socialism of the Right, taking advantage of already-existing nativist sentiment as its people-moving motor, as opposed to the non-existent internationalist class solidarity of Communist mythology), and the kind of Social Democracy that’s grudgingly accepting of capitalism, but just wants to milk it to benefit the poor and disadvantaged.
It continues with the re-tooling of Communist ideology by the Frankfurt school in the late 50s and early 60s, as a response to the no-longer-ignorable failure of Communism after Khruschev’s secret speech about Stalin (i.e. before that, it was possible to do William Seabrook-style cheerleading of Soviet Russia, after that, no longer possible), it continues with the American New Left boomers (formerly the whacky upstarts, now the whacky establishment) in their partial response to the events in the Sixties (both Vietnam as a failure of the West, and things like Prague, etc., as continuing evidence of failures of Communism). It continues with the importation of Frankfurt school ideology to the US, its crossing streams with the strains of mainly French philosophical nihilism (Sartre, Derrida, Baudrillard, Lacan, Badiou, etc.), and continues on down to the rise of “grievance-based” politics, and more latterly ideas like “intersectionalism”.
Perhaps because I’m a former socialist myself, I’ve always cherished the luxuriant garden of whacky Left-wing ideology and maintained an interest in following its twisty path down the decades. That’s why I can tell you straight up that the lunatics are now thoroughly in charge of the asylum. The social sciences and humanities are now rotten with quasi-religious ideological twaddle.
