I don't think I'm ever going to take the word of "anonymous sources" as fact again after the past several years, so trying to reserve judgement.

That said

Harris and Flournoy’s defenders also note that women in power—Black women in particular—are subjected to standards that men often don’t have to clear.

In at least 4 cases in my life, it's the opposite. Many women in power turn into vindictive and petty monsters who will go out of their way to make someone's life miserable because of some slight (real or perceived) - and God help you if you actually try to push back against their ideas (no matter how terrible) in some real way, while guys pretty much always just play it straight. And, Kamala being vindictive and petty is something I absolutely believe to be true.
