“Le Pen recently called for banning the wearing of the kippah in public….”
So one can wear a hat. Besides, many of the religious Jews in France are Sephardic, who follow the Beit Yosef who says that a head covering is a Middat Chassidut (siman 8 IIRC).

I see Le Pen as good for the Jews. Reducing assimilation and reducing physical threats from those who are most threatening.
