I am sure that they will not lead to “Christian theocratic values in public policy” in France. That value system is fringe in France, one of the most irreligious and historically anti-clerical cultures in the world.
Among people who identify as Christian in France, the ones who could be described as radical or fundamentalist are a very small minority.
My observation is that there is a big resurgence in supremacist politics and the main identity involved is white Christian male. Maybe it’s not yet big in France but that’s what I see gaining momentum in many parts of Europe and North America.
You’re talking about a completely different thing, right-wing populist neo-nationalism based on an idea of European ethnicity and culture (which, of course, includes culturally identifying as “Christian”). This isn’t the same thing as being based on religious doctrine.
