Last big immigration wave is happening in Germany for almost 50 years (Austria is probably similar) and, considering negative birthrate, it's clear that in a few decades there will be less Germans (or Japanese, as both countries - ironically - lead the statistic). Under these circumstances, it doesn't seem logical to (still) ask foreigners dumb questions.

Not a few of those who asked me that question (or the version you quoted) have lived in other countries and are otherwise open minded. Still, probably subconsciously, they see someone (even if s/he's white) as some kind of different person. Yes, US/CAN/AUS are different and that's why their birthrate is sinking but it will not get negative in the coming decades.
