As I'm sure you are fully aware, sometimes we find that certain concepts don't fully match reality as it is, and we then have to work to update our conceptual frameworks.

Is it that hard to imagine that "woman" and "man" might be one of those concepts? Especially given the amount of scientific progress that has occurred in the past few centuries?

Not saying I have all of the answers. It's just interesting to me how some people seem completely closed off to the idea that we may need to improve our understanding in this area.

It's curious how politics and activists tend to approach definitions backward. Anyone who aims to be rigorous (as politology and sociology should be) knows that you first must define clearly a term and then reason about it. Instead, we usually see attempts to redefine well-established terms, not by adding an additional meaning, but by replacing the original one. In a purely rational reasoning system, this change would be irrelevant because the important thing is the meaning, not the significant. But we humans are fallible beings, and we tend to transfer the perceptions and logical conclusions attached to the meaning to the significant itself. This way, when a redefinition is done in a society, the term will drag for a while the concepts related to the old meaning. This is a powerful manipulation weapon and I think it's the reason why it's so prevalent in those fields.

This is not saying that you shouldn't redefine anything. As you said in our daily lives there are a lot of terms that have lossy definitions that don't match perfectly with our mental models. But you should be cautious with the real intent of the redefinition, especially if it comes top-down.

The reality and the science is very clear. What you're saying is that science should be adjusted to take into account people's feelings.

That is not science.

And it's only being made more ridiculous when the proponents for the fuzziness of the concept of what a women is also insist that there are a multitude more genders and that you can change between them on the fly several times a day.

If the science is so clear, can you help me understand? Why do trans people claim what they claim? Can you point me to the research?

I need a more detailed explanation than “they have a medical disorder”.
