No one says you have to be dominant and manly. I just don't like the idea that my 'role' is supposed to be wife, mother, and housemaid. Bullshit. My fiance likes cleaning more than I do, and I happen to LIKE working for a living and don't have much of a desire to be a full time mother. I want kids, yes, but I'd happily go back to work at least part time when I have them. Do I think that makes me a sad, miserable person? No. I'm defining my OWN role as a woman, not society's, and I think that's a lot better.
That said, my fiance wants to take parental leave for six months when we have kids so he can stay home. I suppose that's wrong too, because it's not traditionally a male role? Well that's what he wants. I'm happy with that, because I want to work.
