Anti-Semitism is back. Not just as a nasty little fringe sentiment, and not just in the Breitbart comment sections. Not just in social media either, although anyone who posts or tweets and has a Jewish-sounding surname (and even many who don’t) has had to get used to the fact that social media is a perfect conduit for language that would once have been too filthy to use.
The best antidote is not to care; that is what the “block” button on Twitter is for. But when the sentiments begin to creep into mainstream institutions in European countries, then some deeper analysis is required.
