I just don’t get gender identity. I don’t identify as any particular sex, I know I am a particular sex because of my reproductive system. There are only two sexes because there are only two gamete types, even if not everyone ever born will neatly fit into one or the other but that doesn’t mean there’s more than male/female or that male/female biology is purely a social construct. I don’t identify with 1950s gender stereotypes because I think gender stereotypes are istophobic. I think everyone should be allowed to express themselves without being forced into boxes or pressured into life-altering medical procedures without understanding the consequences.
Or, in modern gender speak, I think every person is their own unique gender. (So we should abolish pronouns and just refer to everyone by name.)
