Counterpoint: all my french Jewish friends have reported no such thing. The group is not large, but relatively diverse, spread across 2-3 almost disjoint circles.
French Jew here. Antisemitism exists in France, like everywhere in Europe - we have some history about that going back at least a millennium. But Israel's propaganda interpretation of what antisemitism is and how much of it exists is laughably exaggerated... And it is used as a pretext by the far right to discriminate against Muslims.
The French far right only cares about anti-Semitism, women's rights and even LGBT+ rights when it allows them to bash immigrants and Muslims.
In a bizarre twist, activists from the far-right National Rally party set up a fake LGBT+ association that marched in the Paris Gay Pride parade with anti-Palestinian slogans.
It was such a mess that they were protected by three rows of riot police.
You'd have to be very naive to believe that such false and hateful people could be allies to anyone.
We sometimes make fun of Americans, but we also have some great bingo cards too.
How would people they are passing on the street know their names though? Even then, not every Jewish person has a Jewish sounding name, just like not every Jewish person is visually identifiable as such.
