> Interracial relationships are always a touchy subject.
In the US, very much so, that much I can confirm - I haven't traveled to the rest of the world, so grain of salt. :B That said, it's actually much more common place as a trope than you'd think - just that outside the US it's far more likely to be couched in cultural differences than it is ethnicity or race (I know, I know, put away the Venn Diagrams).
That said...
> The former focuses on White man/Asian Woman, the latter on Black man/White woman. (...) While the former seldom ever raises controversy--
That the trope exists probably means there's enough examples to put a lie to that alone, but even without that it strikes me as just... not true? Not sure if it's my own small reference pools, but there's a particular type of white guy who is Very Emphatically Weird about their "preference" for Asian (i.e. East Asian) women. I believe the (highly unfortunate) term for it is "yellow fever"?
> And works that focus on the inverted gender versions (ie Asian man/White woman and White man/Black woman) are astonishingly rare and far between.
I'm also inclined to disbelieve this about the latter of this sentence, though for... entirely different reasons.
