I get what you mean, but this manga is also set in a modern era world, where women seem to be working as hard as men.
That's not the point-- the point is that man is cursed, woman is cursed, humans in general have invited into creation this curse of death that promotes sufferings of various kinds, and all their suffering is naturally bent towards that common destination of death that affects man and woman alike. Putting aside that there's hardly an era where women didn't work about as much as men did even if they didn't do the same
kind of work, the point is that
1. A specific curse pertaining to men was exposited, and
2. Baba Yaga
doesn't point that out and implies that men don't suffer at all
It doesn't matter whether it's no longer applicable (it would still be, especially outside of
urban zones, talk less developed countries); her entire tirade doesn't acknowledge that verse in the first place, so that-- perhaps-- she can talk about how we were able to overcome the hostile environment but woman is still cursed with childbirth pains and disadvantageous relationship dynamics. That's part of how you know she didn't even acknowledge it to start, and it's part of how you know she has a caricatured and idealized idea of "men".
So I don't really think it was necessarily ignorant for Baba Yaga to omit saying that part (also, just exacerbating the difference in women's favour is kinda important for getting supporters for her plan).
I didn't accuse her of being "ignorant"-- I asserted that she was "dumb as fuck". I can comprehend her using rhetoric in a public announcement, omitting and exaggerating as necessary in order to be the most convincing, but it's that she described a world with facets that either obviously no longer exist or never did while very notably ignoring wholesale the suffering of men, while addressing a whole world (where there exists all kinds of people in all kinds of living conditions) as though it was just one context she was addressing.
I don't even think this is the first time this manga has addressed this kind of fallacy-- that's why I was able to have levity as I riffed about Baba Yaga being an idiot that's taking out her traumas or whatever she's dealing with, out on the world.
