While I concur - in the main - with
@Hijinx's post, Greta isn't insane. Yes, she has mental health challenges, but insanity isn't one of them.
As far as the "public aspect" of this story goes, the most disturbing aspect to a very disturbing story is that this young lady has Asperger's. There was an excellent thread on Twitter yesterday that outlined in very clear terms why what her parents are doing in putting Greta on the world stage is nothing short of CHILD ABUSE. (If I can find it again, I'll post the link. It does an excellent job of showing - from a mental health standpoint - why the "use" of this young lady is so disturbing and so unhealthy.)
People who are on the autism spectrum cannot deal with nuance. And they are hyper-literal. To tell Greta that the world is ending due to climate change rings unequivocally real to her. And folks wonder why she also suffers from depression and anxiety...?
C.H.I.L.D. A.B.U.S.E.
That people are applauding her "public life" is appalling.
