The Gender Critical Feminists do make up bogeyman stories about rapists in prisons, trans women disrupting breast feeding groups etcetera.
The Trans lobby though has also been guilty of the same sort of thing. E.g. I am no fan of professional sport (I hope this kills it dead) but to claim that trans women have no advantage over natal women is opinion not fact. The main fault line ion our society is gender, and to claim otherwise is simply wrong. (Not all Trans activists do that, just as not all Gender Critical Feminists are mean).
To me it is heartbreaking that this is not about fixing that fault line. No person has the right to take a interest in another person's gender unless they are their doctor or fancy them and are fussy. That is the issue we should address - how boys are raised to be violent sexual predators requiring female admiration and women are raised to be weak victims requiring male support.
That is getting lost, instead of helping fix the fault line, this debate (the excess of heat, deficiency of light) is making it worse.
