It's frustrating. The arguments go round and round in circles. I would only suggest you keep completely calm and keep emotion out of it. However difficult that might be.
Anyway in answer to that, yes some women don't get pregnant, but pregnancy is exclusive to women. No man can get pregnant.
It's the flipside of the assertion. You have to keep remembering what men can't do, not what woman can.
If you talk about chromosomes, they will being up intersex. If you talk about wombs, they will bring up some fictional woman who was born without one.
You can only say no man has a womb, no man can get pregnant, etc.
"Yes, not all women menstruate, but only women menstruate.
It's completely ridiculous. But that is the way the conversation goes.
Because, of course, when I was trying to conceive, my husband and I sat down and discussed who would carry the baby. In the end we left it to chance. In an uncanny coincidence, it fell to me. Both times!
Talking about who impregnates, and who gets pregnant sometimes carries a bit of weight.
Or asking. "So, since the dawn of time, how did people know what to do to carry on the human race"?
In terms of defending your rights at work. If it's to do with bathrooms, there is a law in place that says even if they have a gender neutral bathrooms they must also provide a sex segregated one.
And also a trans person doesn't have to use the gender neutral one, they can't just turn the ladies into unisex, for instance. With no other option for women.
Sometimes this works, and everyone is happy. Sometimes the trans person seeks validation by using the bathroom of the opposite sex.
