Well I am from Sweden and we have spent centuries digging up Viking graves and calling them Men if they were buried holding a Sword pointing down their body, between their legs. Typical Viking Warrior Grave. Phallic as fuck. Well suprise, in the last decade or so we have started doing genuine physical checks on the remains and like 20% of tested remains were biological women. Turns out 200 years of present day gender roles has fuck all to say about a 1000 year old civilization.
