Is this moving the goalposts

From here:

At, around 15:31 James agrees with Dave (yikes, agreeing with at T R A N S P H O B E, kinda transphobic, James) that gender and sex are facts and troons don't have eggs, periods, and can't give birth.

&

Women don't have periods/can't give birth because of some dysfunction in their bodies which can (sometimes) be cured with medical intervention. Women, by default, can all give birth and all have periods unless some physical deformity/disease prevents them from doing so.
No troon can menstruate (ever) and no troon can give birth (ever)

Sounds like moving the goalposts. Either that or special pleading. After all, there are exceptions to the default, yet he assumes transwomen can't fit into those exceptions because...they are trans? What makes transwomen women who have that physical deformity he mentions? Especailly since he admits that it doesn't always get "corrected"?
