Leftists are reflexively antisemites. No surprise that as socialism has risen in Europe, so too has racism and anti-semitism. Some just want to be contrary and so will sign on to any ideology, even one like Islam contrary to every fiber of their being, so long as it is in opposition to the west.
Then, of course, as you point out, we have the European Islamic Immigrants; who were raised on a diet of anti-semitism from the cradle.
The Socialist roots of antisemitism.
An excellent read, I cannot recommend it highly enough.
Thanks, I’d like to get to that article tonight, if I can.
