The point is women isn't a synonym for people who menstruate even if you ignore trans people.
What sort of answer to your original question did you expect?
If one would do a general survey, most ordinary people would consider sex and gender the same thing. Most of them would also say that they know the sex of somebody they see for the first time. Which is statistically true, because people whose sex and gender don't match are truly a small minority.
>The point is women isn't a synonym for people who menstruate even if you ignore trans people.
For the pedantic I guess she should have said: women who are in their fertile age without health problems or taking medications which prevent menstruation.

People who menstruate is much shorter than your suggestion.
"gender markers" and "chromosomes" are the same thing for 99% of the population. So guessing really is knowing.
> People who menstruate is much shorter than your suggestion.
Women is even shorter and everybody in the whole world understands it.
People who menstruate is more accurate.
This is false.
