They don't give a single shit about women with DSDs, infertile women, or menopausal women. They're only using them as a rhetorical tool out of self-interest. If they cared, they would listen to these same people when they say "stop comparing us to men in dresses."
Trans identified males are not women, not because they fail to produce eggs, but because they are males. Their bodies are, were, and remain organized to produce sperm, whether or not they currently do. You will never see any of these swine mention sperm in their arguments because they can't use it to force a parallel with infertile women, who have never and could never produce sperm.
If they actually had trouble telling the difference between a male and an infertile female, they wouldn't be able to tell who is TME and who is TMA (meaning transmisogyny exempt and transmisogyny affected). According to them, "transmisogyny" is a unique oppression transfeminine people (but not trans AFABs) face. Women, including pooners, are automatically TME because they can't be transfem (sorry, Kikomi). They will selectively acknowledge their maleness to claim special victim status, but play dumb about it when asked to use the proper facilities for their sex.
Trying to argue in good faith with someone playing self-interested word games is a waste of time. You, Mr. TMA, aren't allowed in the women's restroom. Women are allowed, whether or not they're currently able to become pregnant. Cry about it.
ETA: What I mean is that it's a waste of time to argue with them if your goal is convincing them. It's not a waste for JKR to state biological facts, because there are people who might have genuinely been taken in by the mind games and need the reality check.
