Racism = Pre-existing national culture and language is not destroyed enough.
German "homelanders" (represented in the 30's by the Völkisch movement) believed that the liberalism of the Enlightenment and French Revolution lead to an over-assimilation of jews, especially in Baden (the most liberal region of prewar Germany). They claimed that liberalism ("tolerance") allowed Jews to obtain disproportionate influence over German politics, finance, and culture. They said that this Jewish influence was murdering the Real Germany, weakening their Christianity and sacred traditions.
That is, Germany of the 30's represents the modern archetype of "Borders, Language, Culture".
If you listen to how the Right talks about Mexicans, Muslims, Homosexuals, & Liberals, you will hear the exact same idea.
Here is what people do not understand: once the Right gets their next homeland attack (which will give them the political conditions to finally expel their growing list of internal enemies), you will see the violent side of "Borders, Language, Culture".
History is not about linear progress. It always repeats itself.
