Regarding the beauty of modern discrimination that you note. Plaintiffs in these cases almost always lose, because it is almost unprovable and the bar is high (being called the n-word for example isn’t sufficient). Being unfalsifiable provides little solace if there is no consequence to the discrimination.
You've seen this followed up by threats to resign from the company if the anonymous reviewers' identities aren't revealed? And all this following prior threats of litigation against the company within the past year?
And you saw this from men or non-persons of color who were not fired? Obviously not, but if you do have examples that are sufficiently comparable in your mind, feel free to describe them and make a case. As it is, you're again falling back on unfalsifiable claims.
And I'm still curious to know why you'd expect a company not to fire someone in this scenario?
I posted something earlier about another company and internal emails to a broad mailing list relating to sexual harassment from people in the company. Again, nothing was done there against the people who wrote the email (at least not publicly). And in this case, similar to Timnit, it made national news. Although in that case it was a white female.
From everything made public, her behavior constitutes a fireable offense at any company I've ever worked at, regardless of skin color. And there is precedent for non-PoCs being fired for posting unprofessional messages to internal message boards. So why would you consider her actions permissible?
