Fully agree with this article except that I am of the opinion that the definition anti-semitism ought to include a caveat for institutionalisation. Antisemitism only truly became a disastrous problem when it became institutionalised and legitimised by politics and the media. This is true of all forms of discrimination; when courts of law, politicians and media encourage or fail to discourage acts of brutality, derision and violence against minorities this paves the way to Genocide.

I have posted an extensive commentary on abuses of the term antisemitism at: https://labour-antisemitism.info The articles on that website were what got me repeatedly removed from Facebook.
