@engineer,
That's a fair point, thanks. Striking indeed that these postcards basically ask (to men, who would be the ones voting for or against woman suffrage): Do you want to remain the boss of your wife, or do you want your wife to boss you around? The idea of gender equality as an alternative is completely ignored.
Edit: And yes, that false dichotomy is still being peddled, with the related (false) idea that a
feminist man is necessarily a "
feminine man", a "girly man", ie weak and submissive.
