When is a "Refugee" not a Refugee?

Isn't this odd --

1) Illegal aliens from Central and South America (and from all across the world, actually) -- from countries which are poor, certainly, but in which people are not being murdered for political reasons -- who, were they actually "refugee", have traversed any number of "safe" countries, in which they were required by "International Law" (such as it is), flood into America ... and the leftists insist that they are "refugees" who *cannot* be sent home.

2) The Trump administration is attempting to allow Afrikaners -- white South Africans who *are* being murdered for racist political reasons, and with the connivance of the South African government -- to *legally* come to America as refugees ... and those same leftists mock their designation as "refugees".

Why, one might get the impression that leftists hate white people as much as they hate America.
