“third world flotsam are all the same”
Many Third World people are decent people.
Migrants need to be vetted. The fact that they can’t get along with people nearly like them is no justification to bypass vetting. Most of the world’s problems boil down to lack of relationship skills.
Migration must be managed according to the ability of the nation to absorb a migrant and each potential migrant’s willingness to adapt his new country’s ways.
True. Which is why such people should remain in their home countries. Else, how will their "Third World" countries ever, um, develop?
