Humans are not infallible, so yes sometimes it’s possible to missex someone. This tells us nothing about whether sex can be observed empirically . It most certainly can be, and over 99% of the time, we can clock someone at a glance without even thinking about it The shit is hardwired in us because of evolution. Anyone who doubts this hasn’t spent enough watching unneutered animals. If a male dog can sniff out a female in heat that is miles away, then its absurd to think human males can be easily fooled into thinking another male is actually the opposite sex just because of an identity claim.

It's especially absurd to think human females can be easily fooled into thinking a male is a female too. And it's cruel and sick for TIPs to expect girls and women to happily go along with their attempts to fool us about their sex, and their constant attempts to make us feel bad for caring about and being able to suss out other people's sex.

Fact is, for reasons of our own self-protection and the protection of our young, human females have developed an extremely sensitive, always switched-on "sixth sense" that enables us to size up and suss out the sex of others we come into contact with - particularly when those others are adolescents or older. It's part of being on the bottom of the food chain and the prey in the male-female/predator-prey relationship. Women and girls have to be hard-wired to be guard to protect ourselves personally from attack, impregnation and imprisonment against our will - and we have to be hardwired to be on guard to protect the offspring that are so often in the care of the world's women and girls, and all the unborn offspring that a good number of human females will be carrying within their wombs at any given time.

Much of women's natural alertness to sex and our ability to 'sniff it out" seems instinctual, but our instincts usually get sharpened after years and decades of "lived experience."

I've spent a lot of time around old women with a lot of sensory impairments - diminished sight, hearing, memory, cognition - in care homes and it's amazing how so many of them have an uncanny knack for instantly sensing with a high degree of accuracy when a male has come in their vicinity. The hazy outline of a body seen through blurry vision, the rough shape of the shadow they cast, the heaviness of their footfall, the manner of their gait, their obvious and imperceptible smells, etc - there are many cues and tells that even impaired women pick up subliminally and which cause the senses to go on alert and the hair on the back of the neck to stand up.

One of the big problems I have with the trans craze and the new trend of males radically altering their bodies so as to try to disguise their sex, and all the lying so many people are doing about their sex, is that it ultimately undermines the protective, sex-sensing instincts and abilities that girls and women have developed through evolution. Also, TRAs' claim that it's horribly impolite and bad form to recognize another person's sex turns an evolved strength that girls and women have into a drawback and a sign of rudeness. Plus, the constant claims that "you can never be sure" of another person's sex without doing a complete medical and genetic workup causes women and girls to doubt our perceptions and basic instincts. Which is an essential part of gaslighting.

This whole movement is about disempowering, shaming and disadvantaging women and girls in myriad ways.
