"The problem is that people think that being a “woman” is a “fact”, defined by binary biological “sex” - which they also believe to be fixed, objective and factual.

Sex is binary, and it's really not as "complicated" as you and your likeminded pals like to think it is.
"Women" is not a "social category" - if it was, you can bet the millions of women oppressed over the ages, and women whose reproductive issues cause them tremendous pain, and girls who are subject to FGM, and women who are paid less for the same job, and women who are raped and beaten, and women who are second class citizens in their own countries due to religion or politics, would all have identified OUT of their category long ago.
Trans women are NOT women. By definition, they are biological males.
That is a FACT.
And you are of course entitled to your own opinions.
You are NOT entitled to your own FACTS.
