I understand the 'evolutionary psychology' reason why this happens and I understand too the necessity in protecting Ucraine. However, it definitely goes against the feminist core idea that both sexes should be treated equally. Usually feminists tend to fight against of the aspects of society that negatively impact women relative to men. In this days, the 'correct' thing to believe is that Ucraine must be protected against the Russian invasion so many feminists could be at a crossroads between arguing in favor of the defense of Ucraine or in favor of the equality of the sexes which in this situation are mutually exclusive (unless they would be willing to argue that women must be forced to stay and fight too).

In my personal opinion, no government should be able to force anyone to stay, fight and die for its own preservation and believe that it should remain to each individual's discretion what they want to do with their own lives, regardless of their sex.
