Today's Guardian G2 supplement carries a very good piece on anti-Semitism by Jonathan Freedland. It covers most of the main issues - from the fact that Jewish children need protection going to school in Britain today, to the survival and reassertion of the themes of Jewish conspiracy and control, to the deployment of anti-Jewish tropes in the discussion of Israel and Palestine.
I would just make two points for my own part. The first concerns an issue that could well be added to Jonathan's itemization of the shape of the problem. This is that with most forms of racism it is more or less taken as read that, alongside overtly hostile attitudes towards whomever it may be, there will be a culture supporting these of unconsciously prejudicial tropes and/or discriminatory practices. With anti-Semitism, however, the assumption is widely made that you need to be able to point to episodes of openly-expressed Jew-hatred before you have real evidence of anything at all to worry about. The reason for this disparity is never explained. It is one factor in the insouciance with which so many claim that current attitudes to Israel have got nothing to do with anti-Semitism, when it is plain that at least some attitudes towards Israel (and some practical initiatives) have got plenty to do with it - as Jonathan's column indeed shows.
The second point relates to the reception of this piece, today, on the internet. There has been some comment (see here, for example) on the fact that Jonathan makes no reference to the role which the Guardian itself has played in creating an atmosphere not very friendly towards Jews. I offer three possible lines of thought about that. (1) A person can't say everything at once. (2) Some people are better placed to say certain things than others are. (3) There are more and less direct ways of speaking - different ways of making necessary connections.
