In fact I personally do favor, if Germany were to enact a law to "remigrate" (meaning deporting) its migrant communities after decades of what has been publicly claimed as "parallel Gesellschaft" (parallel society, meaning the system failed to integrate the migrants into the main stream society). The parallel Gesellschaft concept is in fact a misnomer for a system of tiered society (class system), where the upper tier is taken by the indigenous citizens and the lower by the migrants and their decedents. Societal mentality in Germany programmed to think in two tiers, the indigenous and the migrants.
Now some members of their politicians publicly claim "I don't have a problem, if 10K young Iranians were to come to Germany, I do have a problem, if 10K young Somalians were to come to Germany", a pure prejudicial stand of a member of the country's parliament.
