Nothing would make Bindel happier (even happier than she is already about this, which is clearly *extremely*) than to see people form ranks to protect the rich white man against TERFs. That's the result she expects, wants to see, and is actively trying to make happen.
That's what those two women are good for, to her: getting a bunch of trans women and trans-inclusive cis feminists to pick a fight with her and her allies, in the name of protecting a wealthy and influential male predator, while also helping her link this cis guy in people's minds with trans women.
