Getting sacked for retweeting an article written by someone else and about someone else is the new reality. In fact, this article is NOT anti-Semitic in the least and Ms Long Bailey was simply showing her admiration for Maxine Peake, the actress, by referring to her as a 'diamond'.
A few lines in the article say that many US police forces learned neck-kneeling from Israeli special forces - that's it.
