That's an interesting article, but I also read this one not two weeks ago, which is explored further in the Guardian articleHalf of all racist attacks in France take Jews as their target, even though they number less than 1% of the population.
The changing face of antisemitism is interesting. "Traditional" antisemitism, if we can call Christian European antisemitism as traditional, appears to be ebbing, while Muslim-initiated antisemitism has spiked. It suggests that liberal democracies, and those who buy into them, are becoming more accepting, and hopefully this can be extended to being more accepting of all marginalized groups. But the Israeli-Arab conflict appears to be a general Jewish-Muslim conflict in Europe, which is sad. Any way you slice it, antisemitism is certainly too high, but hopefully the long term trend is in the right direction.
