Sall has said that it was always going to end up in the High Court because whoever lost would take it there. The difference being of course that Jason has organisations doing all the work and footing the bill, while Sall is, institutionally, completely on her own (obviously she has support but unlike him, she is a lone agent with everything to lose; he takes on no risk except being barred from women's spaces because he's a man, and of course he can still use male or mixed spaces as he pleases).
If I were JKR, or had wealth like hers, I wouldn't fund Sall's costs upfront; it's very important that people see the success of the crowd fund to show how much support she's got, how right she is and how most people feel about it. It's indescribably awful for her, but it's also important that people see how abusive and ruinous this situation is, that a woman could be destroyed because she knows a man is a man... the potential extent of harm and damage. But I would quietly ensure that whatever happened, she would be secure and all right in the end.
Can't believe this has plagued her pregnancy and the first few years of motherhood for her. The fucking irony...
