assuming you didn’t make a typo, this ain’t cute. The signal you’re sending is that respecting pronouns is a privilege you reserve for people you agree with.
It’s more that I’m giving her a taste of her own medicine. She doesn’t extend this basic courtesy to people she disagrees with, so why should anyone give it to her?
Because it isn’t just hurting she/her, it is also hurting the people who want to be called a different pronouns.
So better to keep referring to her cis pronouns every time she/her is mentioned.
