On the topic of left wing insanity, here's another Walrus article on gender, which is actually internally consistent. At least they make their (ridiculous) position clear:
"Miller instead defines gender as a developmental process. “The variety of gender is as rich as the multitude of plants in the plant world,” they add. In Miller’s paradigm, gender cannot be reduced to biology, psychology, or social roles but is rather the way that an individual responds to all of these factors over time. From this perspective, trans people aren’t really so different from non-trans people: we all explore and develop our gender identities as we grow from childhood into adulthood, but some people experience bigger and more visible changes than others."
In other words, the concept of gender as a category is absolutely meaningless.
