The comment section of someone else's article is not a good place for detailed argument. I am not suggesting that language reform should be abandoned, only that it is losing traction because most people find it a distraction not worth the trouble. In my view, activists need to move on to the next big step they can take rather than continue to take smaller steps on a project that is losing popular support. "Every last vestige" feminism (or anything-ism) becomes totalitarianism. During the Terror, the French revolutionaries renamed the months. In retrospect it seems silly, n'est-ce pas?
I won't make the case that language reform pre se is "White feminism." But I do believe that the emerging rift between White and Black feminists is due to divergent priorities, and that gendered language reform, despite the gains already made, has a significantly higher priority among White feminists than among Black ones.
I make no assumption about the author; I'm not into ad hominem reasoning. Of course, I would not be surprised to learn that she is White and that she considers herself a feminist.
