No, he was talking about an imaginary book, if he were to write a book about WW2, that's how it would be.
I recently read an article where there was an outcry because some country or other, I think it was Hungary, opened a "Holocaust Museum" that, *gasp*, actually made reference to other (i.e. some not affiliated with Nazi actions) attempted genocides and mass slaughters as "Holocausts." The outcry was that doing so 'Diminished the particular significance of the attrocities involving the Jews.'
Such whining arrogance and self-absorption tends towards becoming loathesome when you come to realize that they'll never stop talking about "it".
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.
