Just to echo earlier comments.
Whether or not for some it is a fetish, but it fits within what seems to be the driving force of TRAs, to either invade and colonise women's space, services, toilets, or to make it seem socially unacceptable that women only talk to and support other women.
The TRA as an embodiment of the male sex class, dictatating to and over ruling women, would never have been able to gain the power it has, if it wasn't built on the existing power of MRAs.
Behind every word mangled justification is the reality of the threat, women know your place.
