Sex segregation is heteronormative gender dysphoria and against Human Rights. So why keep pushing people to change biology for the sake of satisfying unnecessary cultural sex segregation?!

 Peter Klevius: It's all about freedom not to let "gender" dictate biology

Peter Klevius 2021 book memorizing and analyzing 100 years since English feminist(s) banned women and girls playing football. 

The real "gender dysphoria" is the fact that cultural sex segregation violates the Universal Declaration of Human Rights which states (article 2) that 'everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as (e.g.) sex'. 

Peter Klevius 1979 drawing 'woman'

The very idea that there's a "right sex" for a certain "gender" is itself a heteronormative view (sex segregation) that believes a person's sex decides "gender identity" and "gender roles" - to a point where the person has to change sex to "fit in" with the "gender" that a heteronormative sex segregated society may find appropriate for that sex. Needless to mention that there are no such coherent definitions other than keeping up sex segregation.

If a female mutilates, sorry, "changes", some parts of her body (e.g. by removing breasts, taking testosterone etc.) and is legally declared a man, and then delivers a baby one would expect her legalized man status to still stand, right.

There is a material difference between a person's volatile but always biologically exclusive "gender" and the person's status in heterosexual attraction (the physical and biological process of being attracted to a biological female) - the latter containing both male lust* and female reproductive capability. And although the physical and biological process of pregnancy, delivery and suckling the baby isn't per se relational to males as individuals, it is so via heterosexual evolution - i.e. something completely different from other types of sexual behavior etc. Consequently it's biological essentialism that defines "gender" because no matter its everchanging meaning, it's always doomed to not be the "opposite gender". So e.g. being a biological mother has nothing to do with "gender". The predominant issue is the biological identity of a person compared to the social reality of sex segregation. Or in other words, the Human Rights reality versus the practical reality for individuals trapped in sex segregation..

* To avoid the common bias trap caused by sex segregation do consider e.g. a male fish's lust for female roe even though he never meets the female herself. Or a bee etc..
