Not all Europeans see this as a joke...I am European and I do not see it as a joke, but a rather good attitude to be inquisitive about ones own background Maybe it is the way we (Europeans, but even US Americans) are brought up: the national state and what it means are decisive. Hence, US Americans are not regarded as having to have that claim and are not regarded as Europeans anymore. However, there are also differences: after all, in Germany even descendants of Germans who moved to Russia in the 17th and 18th century and came back after the fall of the USSR in the early 90s, were recognized as Germans. However, in Imperial Russia and the USSR, they were - like all peoples within Imperial Russia and the USSR - always regarded as their own group, as Germans (whereas in the US they became Americans). And when they came back in the early 90s, they received citizenship. For me personally, US Americans of European descent could become citizens of my country again. I do not mind at all and would be even happy, too.
