> A post-operative trans person will display different physiology from what their chromosomes indicate. Correct: they display a physiology significantly different from what they would naturally produce without hormonal and surgical alteration. Gender is a social construct that is expressed, while sex is an inmate characteristic determined by chromosomes (though the vast majority of people express a gender corresponding to their sex). Gametic sex is redundant with chromosomal sex. A person without a Y chromosome will never, ever produce sperm. A person with a Y chromosome will not ever produce eggs. Genuine intersex conditions are extremely rare (on the other of hundredths of a percent) and no one has ever produced both gametes. Gender identity is so strongly correlated with sex that it's reasonable to use them interchangeably. When we say "women give birth", "girls start to menstruate at puberty" and "men experience colorblindness more often" good faith listeners understand the unstated implication that this extends to transgender men that retain functional uteruses and trans women.
