It is nothing short of chilling.
A video, taken on the eve of International Holocaust Remembrance Day, shows masses of French protesters marching down a Paris thoroughfare chanting openly anti-Semitic slogans and calling on Jews to get out of France.
Chants include "Jews, France is not yours!" "Jews out of France" and "The story of the gas chambers is bull***!" At one point, in a show of raw, seething hatred, the crowd simply spits out the word "Jew, Jew, Jew!"
If anyone had any doubts about the level of growing anti-Jewish racism in Europe the video above should put those doubts to rest.
It's all about the slow drip, drip, drip of anti-Semitic anti-Zionism as it drizzles out of the Arab world and is spread among western progressives who tell one another that Israel is a racist, colonialist, imperialist, apartheid, militarist, racist regime and that "Zionists" - otherwise generally known as Jews - are a scourge on society. Furthermore, progressive anti-Semites agree with hard-right anti-Semites that the Jews and the Israelis have far too much nefarious control over governments and media throughout the west.
And, needless to say, if Israel is half as horrible as they keep telling us that it is, what does that say about non-Israeli Jewish supporters of Israel?
It means that you are immoral.
And that, of course, is the great irony. The people marching in Paris crying out "Jew! Jew! Jew!" do not think that they are doing anything wrong. Quite the contrary. They undoubtedly believe that they are fighting the good fight against a vile enemy.
Of course, that vile enemy happens to be you.
