And that is not ideas of what femininity and masculinity are,explain how dresses are girly or the colour pink or certain music taste,makeup for example are biological ideas lol, also when those things were done (hunting or child caring) at that time they weren’t seen as making you more lady or man like it was just playing with your strengths.Women would hunt when needed or if it played with their strengths at that moment.In modern day society where men don’t hunt what’s your argument on gender roles??
