Nepenthe, I like your posts a lot. They tend to cut through the BS and take no prisoners without being a dick, which can be pretty rare here. I also get your personal stake, and I don't want to try to argue against any of this, but I don't think it's as simple as you're making it out.
The negative perception of mental health is a real issue that needs solving too.
While the majority of the time you see "mental health" used as a defense I'd be right with you, most of the time it's a bullshit and lazy defense, there are times however that mental health is the primary driving force not racism and that leads us into two important conversations that cross over.
Sometimes it is important to highlight both and discuss both, this may or may not be one of those times but there's enough evidence to suggest we should consider it. For now at least...
No, of course not.
You will never find me on a video of a person losing their shit at a Starbucks because they go the wrong order, going on a racist tirade, and suggesting "they may be mentally unstable". It's a bullshit excuse for the majority of cases.
I've explained why I'm taking a stance here, though.
I'm not suggesting we brush the racism away, I'm saying here there seems to be the need to two conversation, or one that combines both aspects doesn't just dismiss the other.
