Südlander or Mediterranean is not a race. Südlanders are same race as ethnic Germans, so Germans cannot be racist against you (they can be xenophobic, but not racist). 

On the other hand, Südlanders get far far better treatment than real Non Whites ( Africans, Asians, Indians) because Südlanders totally fit into European beauty standards (if not often held as beauty ideal) - which is a clear privilege, albeit positive racism. They receive far better treatments in every walk of life - recruitment to dating to house rental to social engagement. Get over your sense of victimhood. Germans are far more sympathetic, cooperative and collaborative with Südlanders than they are to real Non Whites.
