People that get invested in fiction and examine fictional lore need to learn how to tell the difference between which lore is actually important to the series and which lore is an excuse for something.
If Dwarven women are capable of growing beards, but have cultural reasons not to, that is an excuse that they made not to give them beards.
If a female character can only wear skimpy clothing for some given reason, that is an excuse to sexualize her.
If an organization can only be populated men, that is often an excuse to not have to create female characters.
Its all made up. It isn’t a foundation of the universe that they can’t control. They wrote it to be like that.
