If you check a dictionary, the top definition for "woman" is typically something like "an adult female person" or "an adult female human." So the claim that woman/man is a totally different thing from male/female is pretty novel.

Indeed, I bring this up elsewhere, but there's been a lot of overlap of the medical and the social throughout history. That's changed recently. I don't see how that makes things "ridiculous" to quote GP.

How widespread are those changes though?

The Wikipedia article on Sex Differences in Humans uses the terms man/woman and male/female interchangeably[1]. What little I've seen of the scientific literature follows this convention as well.

It's my experience that, across a broad swath of American society, that many people follow the old convention as well.

To be honest, I'm not quite sure of the point you're trying to make here.

Yes, in most contexts in present western society, male/female and man/woman are interchangeable (and certain groups have a vested interest in maintaining this state). There are however contexts in which they are not. Trans people (and allies) need to be cognizant of these things to be able to discuss the differences.

If your argument is that to an observer, "trans women are women" could be interpreted as "trans women are biologically female", then sure one could interpret it that way. But in the context of discussions about trans people, women and female mean different things, which is why "trans women are women" is the phrase, and not "trans women are biologically female".

That dictionaries haven't caught up is kind of disappointing, but if you look at the wiki page, it mentions trans women at the end, which seems kind of strange to do in the context of biological female-ness.

I'll also note that because it's so common to conflate the two, that I try to explicitly add the "biologically" modifier when discussing bio sex. in contexts not talking about trans groups, I'm sure I've conflated the terms without noticing.

My point is that the idea that there is this (clear) distinction between sex and gender is not universally accepted and that there may be some reasons why people are skeptical of it.

In terms of the science of sex differences, my understanding is that they (at least sometimes) don't make the distinction between sex and gender because many traits and social behaviors that we might assume to be part of "gender" end up having a underlying biological component as well (that isn't easily separable).

In terms of the general populace, I would say that for many people the realities of their biological sex (including their reproductive capacity) have a great deal of impact on their gendered experience.

This is not to say that the experience of trans people should be ignored. But this may help account for some of the surprise people express at statements like "trans women are women" or "women is not a sex".
