I've said this before elsewhere but i sincerely believe our downfall was creating a movement centered on self-identifying language. There's ofc merit to the freedom to express one's experience succinctly and be taken seriously, however we put so much power solely in theory over lived experiences and conditions it was only a matter of time before the apparatus was co-opted by people who think all experiences are theirs to try on. Like when white new agers determine it's their religious right to traipse into native sacred places: despite them not also having a historical connection to the land, the technicalities of vague legal and social restrictions make for equivocation to be made between the groups because, technically, they both hold spiritual beliefs that must be honored. We'll just set aside the lived experience of having land, life and culture devalued and robbed at every turn and operate on the false notion of equality being measured from a baseline for all peoples. Honestly this is exactly how appropriation works, and it works REALLY WELL.
Tl;dr we've once against ignored the base to prioritize the superstructure.
