Because if playing a female character confuses young boys’ genderes, surely playing a mal characte will certainly not confuse young girls in their gender identities.

You see, that’s the neat part: this would never even occur to them. The thought that there could potentially be such a thing as trans men doesn’t even occur to these people. And when it does, they think of them as poor misguided victims, because of course women would jealously desire to become men, the superior sex. Everybody wants to be a man, obviously.

One of the reasons that they’re so obsessed with trans women is that the very concept that someone would actually prefer to be a woman shakes the foundations of their patriarchal view of the world and its rigid gender binary.
