Skaven - not yet discussed, are there female rats amongst the clanrats? The stormvermin?
They exist, but have no rights. Skaven call them 'breeders' and treat them as nothing more than baby factories. To the stage that all breeders are locked up in their own section of the city and do nothing but raise young. The skaven are very sexist in this regard. However, far fewer female skaven are born than males. Only, oh, about 10% of the skaven population is female. They give birth to large litters, though.
To the High Elves, there was an interesting discussion about this at Asur.org a
a while ago. You can find my thoughts from about the third page on. To summarise, it is my opinion that the High Elves, when it comes down to it, have a very strong sense of gender roles, and it is quite likely that they, as a patriarchal society, believe that women are inferior to men.
I would say the same applies to Bretonnia and the Empire. They are patriarchies. At their level of technological development, it would be damn weird if they
weren't. In both of them, and in all the other human nations, women are considered inferior to men. Obviously the degree to which this is true changes from nation to nation. Bretonnia is quite conservative, while Tilea is on the progressive side of things.
Speaking of Bretonnia, actually, KotG describes this at some depth, which I enjoyed because most Warhammer materials refuse to even mention these issues. In Bretonnia, women are considered weaker than men. The code of chivalry dictates that the strong protect the weak. The way this works out is that Bretonnian men, specifically knights, are required to be extremely courteous and accommodating to any woman they may meet. They are expected to bow and scrape and open doors for them and pull out chairs and always give them the best of everything, for which the women are supposed to be grateful. 'Great!', women might think, and indeed women of other nations usually feel quite flattered and pampered the first time they come to Bretonnia. It will be soon be noticed, though, that this is done under the understanding that women are going to meekly accept this treatment, sit down, and shut up. If a women has an idea that she wants to put forward? 'Please, Lady Annette, the men are talking.' Very patronising, and the woman will immediately realise that, for all the deference she may enjoy, she has no actual power. Many Bretonnian women think that this is right and proper and balk at the notion that the two genders should be treated equally! Others don't like it, and have figured out that the only way for women to get out there and actually achieve anything is to pretend to be a man. This is surprisingly common. There are female knights, female lawyers, female minstrels, and so on, and nobody bats an eyelash.
It's a cultural thing. People get very good at seeing only what they want to see. A foreigner might say 'what? But look at her! This knight is obviously a woman!', to which a Bretonnian might say 'bah, nonsense! Look, this person is clearly a knight. I have seen this person slay enemies on the battlefield with my own two eyes, and have noticed that he is very valiant and bold. No woman could possibly do that. Therefore, this person is clearly a man.'. Despite this, many people, especially peasants, do in fact notice. There's a town in Gisoreux, I think, or maybe Artois, that used to have a problem with a Chaos cult. Cult members were marked on hidden places on their body to show their allegiance to Chaos. To solve this problem, the villagers simply had everyone in the town strip naked and parade through the village square, which made identifying the cultists quite easy, and it became a tradition that if any person from outside the village wanted to stay in the village (maybe overnight, on a trip?), they would have to strip naked and be examined, to prove that they aren't cultists. When the person is a woman masquerading as man, the examiners have gotten very good at saying 'right, not a cultist, off you go, and no, I did not notice anything strange about that man's body'.
It is obviously not as bad in the Empire. It is nonetheless, I would suggest, a stratified society where women are viewed as inferior to men.
