Why won’t other countries in Africa take these refugees in...are they racist?
The whole PURPOSE of the refugee system is to overwhelm and ultimately displace European populations in their native lands.
Forget about why not Africa.
Expand your thinking. Why not China? Why not Japan? Why not the Philippines? Why not Taiwan? Why not India, Southeast Asia, Arabia, South America?
The only way to predict WHERE the UNHCR is going to send their "refugees" is to measure the percentage of the resident population that is of European extraction. Period.
