First women participated in it. Bring the white feather, Catherine the great and other historical women who were not better than men(sometimes even worse), lot of women support the military and traditional gender roles.

The traditional gender roles are explained due to biology, men didn't invent biology's rules.(btw i dont think it is a reason to defend them because we are able to go beyond biological limitations),

It is sexist to assign specific virtue to a gender, saying men are violent or evil is the same as saying women are weak or nice. Isn't feminism puropse to see beyond genders ? If we can judge all men due to what some men did we should also be able to judge all women according to what some did, would that be fair ?

Last, even if it were true so what ? Isn't striving for equality means that the goal is to erase all inequalitis for everyone? Then using the causes of said inequalities to not adress them is an invalid argument.
