How rare it used to be to hear overt anti-Semitism. You’d sometimes see it in subtitles when masked Hamas types or Slavic nationalists were on the news. But you’d almost never hear it in English. Not in Britain. Not, at any rate, until now.

The rise of Jeremy Corbyn, the aged Marxist who, incredibly, is the strong favorite to be elected leader of Britain’s Labor Party next week, has changed all that. A number of his supporters turn out to be undisguised Jew-haters. They don’t bother with the usual sophistries (“It’s not Jews I have a problem with, only Zionists…”) They give it to you straight, as the following selection of quotations, taken more or less at random from the Twitter accounts of Corbyn supporters in the Labor Party, demonstrates.
