That's not a thing that you can do on twitter where your gender is already public. It's not her that would be intentionally entangling her gender with the ideas that she's expressing, it's her that wouldn't be able to escape her gender being entangled with the ideas that she's expressing.

I'd venture to say that most racial/ethnic minorities try to stay within the pseudoanonymous assumption that everybody on the internet is a white man as long as possible. If you're posting on the internet as a public person, that's not an option.
