It can't though.

This is not because the Imperium or GW views women as inferior, it's because gene seed simply was created from Primarchs who were male, and it was made to work with a male, nonmutated human's body. This is not some subliminal message saying that girls are inferior, it's simply a difference in biology. To add to that, messing with gene seed to that extent would likely be heresy of the highest order given the Imperium's attitudes towards innovation and the demigod status that the astartes have.

If that doesn't work, then just go ahead and think of it as just one more crappy grimdark thing in Warhammer.
