That is edifying, but not the crux of the question.Basically, identifying as some gender other than the one 'assigned' to you on the basis of your sex.
It used to be that if you rejected gender roles associated with your sex and stereotypes of masculine or feminine traits, you were just gender nonconforming. If you had persistent gender dysphoria you might transition (socially and/or medically) to cope with it. Otherwise you were just gender nonconforming and expressing this helped to break down the rigidity of stereotypes and sex roles.
Now if you are female, describe yourself as a woman, and use female pronouns, you are stating that you identify as feminine (and since gender is often defined as socially constructed roles, that you accept the feminine role). This return to saying that women who are not feminine are not women and men who are not masculine are not men is apparently 'progressive'.
Although, I am heartened to see "masculine" and "feminine" being re-introduced into the discussion, as they seem to be the words that many seem to be substituting "men, female, woman, and male" for.
