So no racism claims are valid without either AV recording or, in all statistical likelihood, a non-Black person vouching for her?
If you actually what you want your ethics around this situation to be about then expect POC to start coming to work 24hr recorders on them at all times, just like how recording all police stops is a thing, because that's the kind of world you want to live in.
To my saying "plausible doesn't mean actionable," you jumped to the following conclusion:
> So no racism claims are valid without either AV recording or, in all statistical likelihood, a non-Black person vouching for her?
I thought it was necessary to find some foundation on which we both agreed before addressing your conclusion. If we didn't at least agree that the concrete example wasn't legally actionable, then our viewpoints would be too disconnected to make the effort worth it.
How about this: if there is a "he said she said" situation where the accuser believes the accused did something racially motivated, and neither the accused nor the accuser have any evidence other than their word, should the accused face a real consequence?
