A woman can be an engineer; a man can be a nurse. A woman can be aggressive; a man can let a woman take the lead. A little girl can play with toy trucks; a little boy can play with dolls; A woman can have sex with another woman; a man can have sex with another man. Feminism regards gender roles as social constructs, essentially as customs that a society can choose to discard. Feminism has to be seen within the context of equalities, that is the ambition to establish gender equality.
Transgenderism seems to take the opposite approach. Instead of saying that gender roles are irrelevant they say that gender roles are dispositive. Transgenderists even goes so far as to reject determination of sex at birth, saying that we won't know the sex until the child starts to exhibit gender roles. It should be noted that about 1% of live births are intersex.
Transsexuality or transgenderism has existed since ancient times. It was studied scientifically in Germany during the interwar Weimar Republic. Magnus Hischfeld founded the Institut fur Sexualwissenschaft in Berlin. His theory went beyond the idea of a third sex to a spectrum of sexual orientation and gender identity.
So, are we moving beyond inequality and binary genders? What does philosophy say about this?
