While there are toxic elements of the fandom and weird sexists who take things way too seriously, Warhammer 40K is the dog’s bollocks. Fuck anyone who wants to cry about lore accurate bullshit, the whole point of the setting is you get to make your own lore for your army and nobody gets to tell you if it’s right or wrong, your army is yours to do with as you please. GW has even made posts and statements specifically telling the chuds that they are wrong and to fuck off. My chapter takes all who can prove themselves worthy of having the blood of Sanguinius coursing through their veins and are willing to bear the mantle of The Exploding Suns (suns… suns… suns…) to join them on their epic and calculated journey through a time loop to stop reality from splitting into a thousand pieces by an unseen warp manifested entity shuffling the variables at every beginning and every end, as Chapter Master Astraeus Aqua Forta and his benevolent warp born AI, the only conscious entity to hold the memory and knowledge of surviving intact through every loop, The All-Mother, lead The Exploding Suns across time tainted by time over and over again, falling from the warp onto the deserts of Baal, telling a tale to Dante which he had already seen as visions from the warp, finding and rebuilding the chapter and recruiting his child self to be sent back through the warp to continue the mission, confronting the startling revelation of memories robbed from him during his time in the sarcophagus, and fighting his own desire to end his suffering and struggle before it can start, but at what cost? Could it even be undone? By being in that moment has he already made the choice of damning himself to endless duty? Is it worth the price of all of reality… Hoping to find an end, or stopping one from coming for as long as they can, will the endless turns of deciphering and unraveling the seemingly unending threads of time and destiny weave a tapestry of hope, a future beyond this endless past, or are they forever to stand stalwart against what would be the last deluge of destruction the universe will ever witness? Are they merely souls damned to die again and again in a forever hell known as purpose?

While they are stuck in a loop experiencing endless time time and time again, all-mother fuckers ain’t got no time for any Emperor damned misogynists or incels. My army is made up of men, women, trans folks, non-binary folks, and whoever doesn’t die in the sarcophagus, really. They will even work with xenos, they’re not heritics, but their mission is bigger than the Imperium, and perhaps even The Emperor. If anyone wants to fight about it they’ll just throw an exterminatus at the fuckers or have Dante tell them to mind their own fucking business and cut all their dicks off if that isn’t something they already do to themselves, 40K is weird like that.

The lore in 40k only exists to get people to buy little plastic soldiers. People read about their plastic soldiers in the lore and they want to go buy them.

GW can and will change lore in order to generate a profit.

And yes the 40k lore can be really interesting.

Very, very, iirc, but likely one of the reasons women in 40k aren't space marines is that they are genetically enhanced, as well as have multiple organs implanted. I would assume the whole gene splicing piece is probably the hangup.

Again iirc, they are pseudoclones of their primarchs who are pseudoclones of the big E.

I would assume a trans woman could be a space marine then? They probably would never know they were trans though, the life of males that eventually become space marines aren't exactly ones with enough space for that kinda introspection just a constant struggle to survive in some of the most hellish places in the Imperium.

There are also the Adapteus Sororitas, plenty of women in the Imperial Guard, and honestly brutally bad ass women all over the 40k universe.
