Both the right and left have confused and disordered the subject of imperial colonization

Africa is the most recent audacious example of this, where the capitalist's colonized Africa and then later the left called for decolonization, which led to bloody African dictators and a big fall in the standard of living for all except the dictators. Now China, the new imperialists as national socialists, have blocked their people from any objection to getting at the large resources of Africa.

Let Africa be Africa! But then do not accept immigrants fleeing to Europe and America as the consequence of Africa being African. Let Africa work out its own problems!

The same common sense goes for letting ethnic groups be ethnic groups in their own ethnostates across the world; don't try to colonize them with imperial arrogance and greed, but then, do not accept fleeing immigrants who naturally will not assimilate into different cultures.

In any case, reality points toward the long term political/cultural solution of an ethnopluralism of ethnostates, in America, Europe, China, even in Africa which has always tended to go that way anyway---with some sort of federalism mainly devoted to protecting the independence of ethnostates. That is the political/cultural structure most in harmony with real human nature which developed many thousands of years ago and remains kin-centered, gender defined, ethnocentric, even xenophobic, among other conservative things, with group-selection as the primary unit of successful selection, followed by individual selection. All else is mainly political propaganda.
