It's not the story of Space Marine I'm worried about. It's the following scenario:
Vidya/Novel/Comic book/what have you gets some form of woke cancer shoved into it by rainbow haired idiot (Female Marines, Troon Marine, Nonbinary Character, what have you)
Woke idiots on Sigmarxism and Feminist40k raise a stink because "it's cannon now!" and renew demands for "representation" in 40k
Woke idiots in BL/GW Proper use the external pressure their allies are creating to amplify internal pressure to let them add woke cancer
GW releases special edition model of the woke cancer, making it cannon.
Basically, backdooring in the wokeshit to the actual lore proper. Hell I remember when one of the EU White Dwarfs accidentally included pictures of someone's kitbashed Female Ultramarines, and it took exactly 0.00015 seconds for plebbit to start explaining to everyone that it's canon now and we can all suck their feminine penises.
