Funny how you maggots appeal to then dictionary when it serves your purpose but not so much when it doesn't.
From your usage guide
"Among those who study gender and sexuality, a clear delineation between sex and gender is typically prescribed, with sex as the preferred term for biological forms, and gender limited to its meanings involving behavioral, cultural, and psychological traits. In this dichotomy, the terms male and female relate only to biological forms (sex), while the terms masculine/masculinity, feminine/femininity, woman/girl, and man/boy relate only to psychological and sociocultural traits (gender)."
So the terms, "...masculine/masculinity, feminine/femininity, woman/girl, and man/boy relate only to psychological and sociocultural traits (gender).". So gender reassignment surgery is a reassigning of the psychological and sociocultural traits of gender. Im not doctor but I wonder why they have to lop off breasts and penises to reassign psychological and sociocultural gender traits?
People opt for cosmetic surgery quite often to feel better about themselves.
Are you saying that all cosmetic surgery is wrong?
Should we outlaw breast enhancements and breast reductions? Make it illegal to remove a breast to prevent cancer?
