We have a word for woman because it is a useful descriptor. The intention of the category is to presuppose useful information about a person. In some situations it is necessary to define. No need to answer the if not question.
Well if someone says to me "that woman is suspicious" and there are two people who present as men, and one who presents as a woman, then I'm going to keep my eye on the woman.
And what specifically about her presents as a woman to you?
It's funny you're such a coward about actually saying this, since you're the one claiming this basis exists. If it's there and you can know it immediately on sight, then what about the woman you're imagining in this scenario makes her a woman to you?
"Vittually everyone else is using a definition," so what is it? You refuse to say directly. And how do you know everyone else uses that definition? Multiple people itt have defined it as I and Erin have- any woman who identifies as such.
No, it's that they fit the gender binary you've been trained to spot your whole life. However, we've found that the gender binary is inaccurate and wrong so it's stupid to force people to follow it arbitrarily.
I am reading what you're writing, I just disagree and you think I should agree. No thanks.
