I didn't mean racial purity, rather how specific German culture and the German language with all of its dialects is to Germany.
Its not very globalized like American culture.
Kids who grow up in Germany will grow up speaking the local dialect of German and internalize the local culture. There's not much of a problem there. That is, unless you are someone who thinks that language and culture are tied to race. While I am not suggesting that you personally think this, it's an idea that clearly lurks in the background of these sorts of concerns (as you can see elsewhere in this thread).
