@RealTayChaTLC Right, let's do this.

Sex is *observed* at birth by “reading” external genitalia, which is a remarkably sensitive marker of sex. Sex is also now routinely observed in utero, again by “reading” external genitalia and, increasingly, by DNA analysis.

@RealTayChaTLC The definition of female is: of or denoting the sex that can produce large gametes.

This not a matter of *observation*, this is a matter of *definition*.

@RealTayChaTLC Very few animals and no plants menstruate, yet females exist across almost all complex life.
We do not become men at menopause. We certainly don’t “revert” to men, which implies we were men at some point before menopause. Maybe you think we are men before menstruation?

@RealTayChaTLC Sharron Davies is female. That means she is of the sex that can produce large gametes. Putting a penis on her won’t change that.
A man who loses his penis remains of the sex that can produce small gametes. That is, male.

@RealTayChaTLC We may not look between our legs to know *who* we are, but what’s there tells us an awful lot about an important aspect of our lives.
The position that it is not fair for TW to compete with and against females in sports is not based on winning (or not).

@RealTayChaTLC Feminism is about female liberation from patriarchy. It is for females.
I don’t think TW are predators. I think some males, under a selfID model, will pretend to be trans to access female spaces for various reasons.

@RealTayChaTLC I will repeat. Sex is observed at birth (and often in utero). Changing external genitals does not change one’s sex. You should review your definition of female ASAP.
