Even the word female is now a "dogwhistle."

From Are women still persons? when sex based feminism becomes verboten

Feminism has now become morally reprehensible to the woke wahhabist left, which, in its jacobin style, has powerful corporate and political backing—misogyny has reached such a peak that the words ‘female human’ trigger a storm of nasty reaction from trans activists, who insist it’s nothing but a common anti-trans dogwhistle to invalidate trans women’s existence. In fact, one book reviewer recently received a directive to stop using the word ‘female’ in her reviews, apparently the word female has pejorative connotations—of course, this is woke code for ‘excludes trans people’. Anyone deemed invalidating to the trans narrative automatically becomes anti trans.
