sigh I don't know why I bother speaking with TERFs.
There is harm being done to the entire class of women for the loss of the concept of sex as the source of female oppression. Sex matters and these distinctions are being removed in language.
Firstly, that has absolutely nothing to do with what I wrote or the chain of comments thus far. It's just a completely non-sequitur accusation.
But secondly, this isn't happening.
An intersectional understanding of oppression and privilege does not erase the oppression cisgender women face.
And the distinctions in language are absolutely not being removed. The words "transgender" and "cisgender" exist precisely to make discussing these issues in a clear and respectful manner possible. That's exactly what those words are for.
