To be honest, this happens in Swedish too, just not as quickly and more based on social class than on physical phenomena. For some reason I don't fully grasp, the N-word is unacceptable in Swedish, despite Sweden having almost no black people at all 50 ago. An Americanism I guess. I wonder how that works in Spanish-speaking countries? But otherwise, its more that "janitor" became "hygiene technician" and such. The Sami national minority in Sweden used to be called Lapps but are now called Sami, but Sami now has the same negative connotations that Lapp used to have. And the Northern region of Sweden, where many Sami live, is still named Lappland.It is a hard issue, due to euphemism threadmill. Any word chosen for this will eventually become a bad word, and be replaced by another well-intentioned word that in turn will become a bad word and be replaced by yet another one.
Human language is just irrational in many cases.
This is as long as I think I should go in this direction, or it will quickly become political.
