Is she, um, trying to imply that she donates her entire monthly salary to charity?
On Jack's multiple 'minority' identities, this may be an unpopular opinion but I personally thinks she steals them from other people. I first noticed this is her writings about her anorexia, which I have had. She had all the jargon and anecdotes down pat, but they were all really cliched and stale somehow, as if she was just recycling them from the dozens of middle class white girl anorexia memoirs that were out there on the market. It didn't ring with authenticity. When she adopted her trans identity, her interviews about it were much more about her dislike of her breasts than her being male. I'm NOT trans so tell me if I'm speaking out of turn here. Likewise her AA identity is all sloganeering.
Like Von89 said, she steals her identities from people she knows or from books. The real Jack is white as mayo Southend middle class tory-lite girl. That's my belief.
ETA can't believe shes done a mini chaos and it's not even 9am yet.
