Gender refers to the socially constructed roles, behaviors, activities and attributes that a given society considers appropriate for its individuals. It is often considered a state of being, a mode of life.
When used to categorize individuals, it can be described as:
- social roles based on two distinct biological sexes (man and woman)
- personal identification based on the reiteration and repetition of the norms through which one is constituted by society and self-awareness (includes feminine, masculine, transgender, non-binary and gender-nonconforming)

one’s internal sense of self in relation to the social constructs of masculinity, femininity and androgyny

Not the same thing as sex. Gender is what you identify as despite what you were assigned as birth. Gender is what you are. While female and male are the most common ones, you also have transgender, binary, agender, gender-fluid, and the list goes on. It is important to respect others no matter what you personally believe in.

Different from sex. Two sexes, many genders/ gender identities .

A broad spectrum of identity. Gender identity varies from person to person.

What you identify with as your pronouns :)

Something distinct from sex that is usually binary but not always. Non binary gendered people are real and valid. A mismatch between sex and gender is what defines transgenderism. Gender is often confused with 'gender expression' by wannabe-inclusive people who don't realise they are actually invalidating a lot of people with this conflation.
