JAPAB, you have made me chuckle this morning with you post at around half 10 last night.
You managed to clearly communicate how to describe a plague that only affected/effected cats with hair without the use of an introduced label for cats with hair. QED no need for the term ‘cis’.
The key difference between trans women and women is biology. Plagues/disease etc does differ according to sex, so in that respect your analogy highlighted a reason for differentiating between natal males and natal females. However, in the case of trans women, they can acquire disease or illness that women cannot get (e.g prostate cancer) and cannot acquire disease that only women acquire.
Again, I think you have made the case for the term ‘woman’ not having qualifiers.
I use people’s preferred pronouns and names. When talking about trans people I usually use the term ‘trans people’ as this is far more inclusive as it accommodates those with non binary and fluid identities.
However, in our society, the terms ‘woman’ and ‘man’ are widely held to refer to natal sex so it is disingenuous and misleading to use it for trans people. I think trans people should be encouraged to accept their ‘transness’ and the rest of society should not be encouraged to pretend it doesn’t exist.
