It is about time for me to make a prediction. Furthermore, it should be a risky prediction, since predicting that the Spring will come is not particularly brave or useful. Since Netanyahu and Le Pen were both disinvited from the "Je Suis Charlie" event, I will stick my neck out and propose that certain parties that began anti-Semitic will find it in their interest to reverse course, just as those which were not formerly anti-Semitic have already found it convenient to become hostile to the Jews.
This isn't to agree that there are "right wing" or "far right" groups in Europe. The term "right" in Europe refers to parochial fascism that respects traditions while demanding massive government intervention, as opposed to universalist fascism which seeks a pan-national, lowest, non-common cultural denominator with a similar per capita rate of perpetually increasing government bloat.
