You assume I'm an SJW, or that I stand for exactly the same things most SJWs do. I don't, and I think a lot of people who call themselves SJWs are great at the social part and terrible at the justice part. I think a lot of SJWs are self-promoters and drama queens.

Your factual observation that one of the causes that SJWs sometimes latch on to is the treatement of the mentally ill is not in dispute (by me anyway). However you've failed to provide a convincing argument that this is to be laid at the feet of the mentally ill, and not the self-promoting drama queens that claim to be fighting for social justice.

To be honest, I think SJW advocacy on the part of the mentally ill is pretty feckless and unhelpful. I don't think you have to worry about mentally ill people gaining power from it, as their methods are far too dysfunctional.
