That is exactly the point, nowhere has Abbott said "Jews don't count". In fact, in that excerpt, she wrote that there is prejudice against white-skinned people.
In real terms, not a lovie PC reality where anyone can be racially abused if they say so, black people have had tonnes of discrimination to wade through that continues today at a far greater extent than white peoples suffer. As I said previously - "to my mind" - this is just my opinion. But I doubt you'd disagree.
However, the idea that there is a 'suffering index' is nonsense. You can't exactly quantify these things, and it is not a competition - which race has suffered more!? And Abbott is foolish to so much as brush this area with the previous in the Labour Party. Just penning the term "jew" is a danger for her politically, with the 'auto-attention' it brings and guns drawn. Rightly or wrongly there is a pre-judgment (prejudice) against her. Had this been said by someone else, a young new MP, the response wouldn't have been the same. Labour is ready to purge the old and is trying to make itself electable. Abbott is always an easy target.
