zambia and nigeria aren't that far away. it's more like going to nyc and worrying about a virus in miami, if people here were more sedentary but with weaker immune systems. also iirc wunderbread is black so you can't use 'jus a buncha coloreds' against her.
Yeah except people from Zambia don't shout "roadtrip" and pile into a car and drive to Nigeria. There is a GIANT EQUATORIAL RAINFOREST in between these two countries (caps for largeness of rainforest).
It's not a "just a bunch of coloreds=racism" argument so much as viewing Africa as a series of interchangeable nations like one would view the US as a series of interchangeable states. Skin colour has nothing to do with viewing Africa as a single entity; people just think that African nations are very similar and what afflicts one automatically afflicts others. I'm not targeting WunderBread here at all, either, I see this kind of thing pop up every time someone says anything about Africa. "Oh no terrorists blew up something in Morocco... but I'm going to Botswana in three months how will this directly effect me?! WILL I BE EXPLODED?" Not quite, but you get the picture!
Zambia and Nigeria are totally different nations that have several nations in between them. True, they may be like New York and Miami in distance, but imagine if instead of an excellent interstate system between those two points you had some of the most impassable terrain in the world. For like 600 kilometers nonstop. It doesn't make for a migration route.
