There not 100 million Dutch people that is why they feel threatened.  Their culture will become assimilated to the new migrant. Though culture do change naturally, an abrupt change is all to sudden to accept for many.  They do have the right to preserve themselves.  How can we be that selfish and demand that they change themeselves.  They will be a people without a country. Who goes around and demands that their own churches,  historical monuments be removed because they offend the new comers. It is madness for the Ducth to accept this.  They should not, it is not racist to preserve their culture, their people.  Loving yourself does not mean you hate others.  What most should be alarmed is the destruction of ancient monuments in Syria, in Palmyra thousand of yearsold human heritage was basically damage by fanatics.  I do believe the response to this is to have more children if they feel threatened.
