I thought that would have come through in my comments- re racism in France re people of North African origin, the old Maghreb colonies- most of them of course, French for generations- but still not accepted. It is a two way thing- many French will tell you that it is because they do not integrate- but it is very hard to integrate when you grow up in awful ghetto communities on the edge of towns, with poor education- and then, even for those that do succeed and do well, find it impossible to find jobs, flats, a loan to start a business, etc, etc, etc. When I have time I'll tell you about a young French woman who stayed with us for a year in the UK- and her family's experiences- it it very very difficult for them in FRance, even with a Uni Degree and good qualifications (which few obtain due to the above conditions).
Marine is a woolf very well hidden in sheep's clothing- which has allowed her a great following. She knows how to market herself and her ideas, and it makes her so much more dangerous for it. At least with her father, you knew where you stood.
Not sure about the answer to the question in the OP. As you said soontobe, she is probably on this side of that line. France has awful problems with racism- and her large following, especially in rural areas- is concerning. Hence my original question.
