I don't think the use of the term real women is unfair Mrs M, so we'll have to disagree.
I don't think transwomen are real women. That doesn't mean I want them persecuted, or don't believe that they are entitled to dignity, respect and human rights. It's just that I don't believe they are women in the sense that someone who has experienced girlhood and the biological reality of womanhood, is a woman.
I'm done bending over backwards to avoid using language that might upset or anger transwomen. I don't go out of my way to do so, obviously, but I won't hedge my language anymore, to spare the feelings of biological XY people from the class which oppresses my class.. I'm prepared to be civil, polite, even kind by using her when I mean him - but I will not describe real women as cis and not pretend that people who are XY with male socialisation, are women. And if we need a term to differentiate women from transwomen, then real seems to me to capture it, though I'm happy to accept a less upsetting term as long as it's not at the expense of reality.
