It would be convenient to have experts to look toward, but I don’t know that there is a one-size-fits-all approach. Even among disability rights advocates, there won’t be agreement about the best approach. The situation is full of contradictions. Britney is absolutely entitled to privacy and should not be pressured to share more about her mental health than she’s comfortable with. But at the same time, the cloud of secrecy that she and her circle maintain and Britney’s apparent resentment at being labeled serve to perpetuate stigma surrounding mental health and disability. Different advocates might have different reactions to the same situation, and they can all be valid in my opinion.
That said, I agree that education and awareness is a reasonable first step and that we should be welcoming the input of experts and creating safe spaces for discourse.
