Le Pen has a long track record, mostly in French, much of it old (pre internet, harder to find)
Most of his FR supporters forget that these racial biases of his would be legislated. Higher pay for racially pure French, better housing, etc. And we're talking citizens here, based on their background, not immigration.
My understanding is that the National Front's program would give preferential treatment to "the French." As far as I know, French Jews would be included in this favored group. Do you have any evidence to the contrary?
