Agreed on having generalized and painted with a big brush a bit.
Regarding LePen the US alt-right and some Keks were trying to paint her as the European Donald Trump. I don't believe that is the case, I believe she is too far right and is not motivated by some of the arguably positive things that motivate Trump. This opinion has been expressed by the likes of Milo Yannopoulos I believe.
As for the French being not open to outsiders, I am not sure that is the issue. The Japanese are not open to outsiders and remain the one country where Islamist Terrorism has not come about.
What the French do on the other hand, is that they are extremely anti-religion. I'm not religious (technically I'm a Buddhist) but I agree with Prof. J.B. Peterson about Judeo-Christian tradition being at the base of all western civilization, and when you hack at your roots, you get these results: marxism and derivatives (post modernism, political correctness, social justice, sexual identity politics, feminism) and at the same time you become vulnerable to being invaded by people who have not forsaken their roots, such as Muslims.
I wish I could say screw France, the rest of Europe is gonna survive. Unfortunately most countries in Europe are at different stages on the same road to perdition.
