There isn't much point of it but humans like to feel they're part of something. Gender was more heavily defined years ago. My sister's mother-in-law proved that when I cut my hair short and she told me I cannot be a girl because I have short hair.
Girls apparently only have long hair and pierced ears, anything else and you are a boy. Girls were defined as only wearing dresses, long hair, pink stuff, fluffy stuff, cooking, cleaning, housework, having children and being no good for anything else. Boys were defined as trousers, short hair, wearing blue, playing football, fighting and working full time and not good for anything else.
Nowadays it really doesn't matter because gender doesn't apply so much. Gender is a variable whereas sex is not. Your sex is absolute whereas your gender is not.
You could be the sex of a female but look like a male, have stereotypically male attributes, etc or you could be a male the other way around. The stereotypes of male and female remain but are much more flexible and fluid than they were years ago.
Because we're born either male or female. It's just the way it is.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
