"The visible decline of so many historic city centers is intertwined with these anxieties. Losing the ancient French provincial capital is another blow to Frenchness — tangible evidence of a disappearing way of life that resonates in France in the same way that the hollowing out of main streets did in the United States decades ago."
And from there the article goes on to talk about loss of businesses in city centers, vacancy rates, and malls. The point is protecting France, not against immigrants, but against the change of lifestyle.
So, my "zero" claim was wrong. I still assert that the gist of the article is very much not about immigration, Marine Le Pen, police violence, minorities, or incarcerations.
