The purpose of a strict immigration policy for many Europeans (and Koreans and Japanese etc.) is to preserve their countries as ethnically based nation states with a clear majority population. There is nothing fascist or racist about that goal. Its just that certain countries are based on having a shared culture, history, language etc.
Believe it or not, immigrants tend to contribute quite a lot to that shared culture, history, language etc. in pretty much every country since the beginning of time.
