So what I was thinking about the people who say that there is only 2 genders and I found that in actually sex and gender is like four layers of a Matryoshka dolls (russian dolls with dolls inside of it).
In the top layer we have physical appearance, whether more mascquline, feminine or androgynous. This commonly ensues gender stereotypes, although the physical appearance is the only layer that can completely change to each person's wishes.
In the second layer we have sex, the anatomical aspects of a person. There is male, female and intersex collectively. As a persons sex does presents physical changes after puberty it leads to sexism and gender stereotypes set by society. It is impossible to change this, that is the main problem FOR trans people but you know they can get pretty damn close.
After that there is Gender, the mindset of a person. Ranging from men, women or the genders in the non-binary umbrella. These are all social constructs, as well as the pronouns cis and trans people use. Gender is quite literally a mindset; the physical hemispheres and brain function can differentiate from a persons sex or gender, that is why there is trans people. Although the idea of gender is very sexist, the younger generation have tried to make it a more inclusive ideology.
And finally sex chromosones, our DNA. You may be aware of XX and XY which are male, female exclusively but there are many variables; XXY, XYY, XXXX, XXYY etc. These are not exclusive and do change a persons sex. People may probably go their whole lives without knowing they are not XX or XY.
You see my thought process is well that of a person who hyperfixates on a Ben Shapiro video because he is an asshole. None of these layers are whole-heartedly related and are entirely separate in their own right. The upper layers however are what people see first and choose over the next layers. Everyone will become more complex the more you learn despite prior thought so yeah.
