My policy is that the second somebody starts broadly referring to women as females and men as males I block them because they’re probably either a radfem or a conservative. Sometimes those two are the same thing.
* women * female * biologically female, if on HRT (I will die on that hill too!) * trans
Using the adjectives as nouns has a correlation with problematic views that justifies investigating further, but using them like this is just flat out misgendering and objectively wrong, because it’s not what those words mean.
