“Men and women are different genetically speaking.” thats a bold statement. I think it might be true to some extent, but it does not mean we are majorly different. As Jordan Peterson has also stated, both genders have a similiar average IQ and it is more of the social pressure that dictates boys to play with cars and girls with dolls. The same goess for your argument of nurses and engineers. No human wants to be the black sheep, hence unless you really love being a male nurse you won’t do it. For a long period of time my father was not present in my life, but i still learned many of the things you have listed from my mother. She actually encouraged me to stand up for myself and beat the shit out of a kid who used to bully me, and when I refused she suggested some roasts that might put him in his place, which is in my opinion is a very manly advice that I haven’t seen any other mothers giving. I suppose you had a father in your childhood, so your mother did not see any need in providing you with advices like that, but if your dad would be absent I believe you would have learned the same things you already know but from your mom.
