I'm not a big fan of diagnostic labels. Every individual is a different case. [disclaimer, worked in acute mental health, and brain injury rehab total seven years, before getting sucked into the software and analytics industries]
I may be seeing this through bipolar-coloured glasses - I don't have it myself, but I have loved ones with it and know very well what it looks like from outside. It's not normal ups and downs of mood, it can be really scary stuff.
The legal case probably didn't help, but it's quite possible there could have been no way to stop this short of someone present on depression watch.
Are you implying that depression or BPD is 'compatibile with blame'? If so, that's absurd.
No one would ever blame you for a [genetic] heart disorder. In the same way, no one would ever blame you for a [genetic] brain disorder. Phrasing it as such removes some of the stigma.
I think that the way to beat the stigma is talk openly about it.
Easier to say than to do. If you're depressed / bipolar / schizophrenic and talk about it openly it can make people very uncomfortable, which can result in their not wanting to be around you, which can result in further isolation for you, which can make your situation worse.
