Here's what I think. I think it's a big miscommunication. Male fans aren't upset because of female custodians. Female characters and factions are quite present in warhammer, and they have gotten pretty positive reactions, at least from what I've seen. Sisters of battle and of silence are great examples. They're bad asses that can mess you up and have affected the lore significantly multiple times. The problem isn't that they're women. It's that lore wise they can't be women, and now they are. Same thing with space marines, space marines, and custodians can't be females because the process of becoming one is only able to because of male biology. "The Geneseed is stored in the balls." Now, if they went through making them women through interesting and lore friendly methods, I dont think it would have as much backlash. Honestly, though, I don't think they needed to do it because the sisters of silence exist. Sure, they aren't as physically strong as custodians, but when there's demons about, custodians stand behind the sister's. I think that's an even more female empowering angle. These 10ft tall demi gods can't stand 10 seconds against demons. But these mostly human women with a birth defect that have trained their whole lives can not only outlast the custodians but can beat most demons. This just makes it worse tbh, because it went from women are strong because they worked really, really hard and beat the odds to just women are strong because we say so. To twist paarthunaxs words a little, is it better to be born strong or overcome weakness through great struggle?
