Some guy named William Lehman has written an essay, Destroy the myth, destroy the culture, that starts off with a reasonable premise and then goes totally off the rails, in an entertainingly oblivious way, and as it’s crashing, invents a new label: the “SJW Glittery hoo ha crowd”. I love it, even though I don’t have a hoo ha, glittery or otherwise. I’m still happy to be associated with glittery hoo has fighting for social justice.
Anyway, the part I agree with is the importance of foundational myths to a culture — we need aspirational ideas, and something to give us a worthy cause. Where Lehman goes wrong is that he identifies with science fiction culture, and proceeds to regale us with a completely nonsensical vision of our foundational myths. Read and be astounded.
