Just the opposite. Can you name any socialist regimes that promote free/mass immigration?
SSocialist regimes promoting mass immigration?
UK(socialists let their country be flooded by “asian” immigrants for political reasons), Spain(Zapatero the socialist PM made a big global amnesty for illegals when he began his first term), France(can be considered as a socialist country since a long time and it has seen a massive immigration )
That’s the “new fashioned” socialism
