I just read an article about the medieval / ancient approach to sex and gender. The writer termed it the 'one sex' model, with 'male' being the normal definitive sex and 'female' being a deficient, broken male. I remember encountering that attitude to women in Catholic theology but hadn't heard it referred to as the 'one sex' model before.
In any case, it occurred to me that TRAs are essentially taking us back to the middle ages by promoting the idea that gender exists on a spectrum and there is no such thing as 'female' biology. It erases the female experience and ignores the biological burden borne by women in reproduction. It silences women from speaking about the specific experience of living in a female body.
It's really no different to how women were treated in the middle ages or by the Catholic church: ignore the specific biology women have, assume 'male' is the default but - the TRA twist - allow said 'males' to define and express themselves in any way they want.
Yet we're supposed to be the ones on the wrong side of history...
