Trans-identified males are obsessed with the notion that they will be raped or abused if they use male spaces.
The reason for this obsession is that, more often than not, they are using porn that depicts women being bound and / or assaulted (or men 'forcibly' transformed into women by way of sexual abuse), which they find sexually thrilling.
It is a masochistic humiliation fetish.
Such men see being a woman as something humiliating. (And by the time they begin "identifying" as a little girl, they've already consumed a substantial amount of BDSM content.)
When these concepts are repeated in the media, the result is not only to validate the fetish, but also to humiliate women, by proxy, for the pleasure of men with this fetish.
