A populist neo-nationalism based upon ignorance of history is bubbling-up at many places in Europe. This shows the importance of knowledge about history, understanding the past, and learning from it. Also, the fact that so many immigrants have become Europeanized, showing that culture is independent from ethnicity, nationality, religion even, is not understood enough. It merely takes a couple of generations to completely diffuse any strongly anti-European feelings among immigrant communities, and this has nothing to do with wearing head scarves.
This is where culture and the understanding of what it is, becomes crucial, as well as the understanding of what European civilization is supposed to be. Rightwing extremist parties in Europe lay the groundwork for fascist outbursts and the destruction of the European idea: its civilizational and cultural unity, and its ability to build bridges and to accomodate differences between groups.
"The fear of immigrants threatens to destroy the very social and political fabric, culture, tradition, religion and way of life that Europeans want to protect."
Culture, in the sense of offering a humanist narrative, should counter these tendencies wherever it can.
