You have oft heard it said that two plus two equals four. For that equation to be true and balanced, it must also mean that four equals two plus two.
You will have heard the dubious inculcation that transwomen are women. If that claim was true and balanced, it must also follow that women are transwomen. But the latter statement doesn’t add up, because women are already women; they have not and indeed have no need to transition from some other former condition.
It follows then that only men can be transwomen, and hence a fortiori transwomen are men.
It is encouraging to see gender critical views being upheld via the Equality Act in the recent Maya Forstater case.
