(Basically, SF is for white, cis hetro males, by white, cis, hetero males. Anyone else is culturally appropriating it.)
The SF field has always been open to everyone at every level, so the basic anti-diversity claim from the Woke crowd is an outright lie. This has been pointed out to them on numerous occasions over the years, yet they persist in the lie, repeat it often and ever louder, thus revealing their own disingenuous nature, and all the while labeling anyone who disagrees with their viewpoint a racist, sexist, homophobe, because these are the tried and true strawmen guaranteed to shut down any argument.

They scream and holler about cultural appropriation when it comes to the white oppressors in SF, yet use smears and intimidation3 to aid in their attempts to appropriate (and thus balkanize–divide and conquer) the SF field in service to the lie born of the double helix comprised of their social/political agenda of non-diversity in the field.
