Or, it could also be that Africans make up ~13% of the US population, and as much as 30-35% of the population in urban America, compared to 3% in France and less than 1% in Germany, and so we're just more familiar with African (American) cultural signifiers.
"As of 2004, French think-tank Institut Montaigne estimated that there were 51 million (85%) white people or European origin, 6 million (10%) North African people, 2 million (3.5%) Black people and 1 million (1.5%) people of Asian origin in Metropolitan France, including all generations of immigrant descendants."

(emphasis mine)
So Africans make up 13% of the population in France as well (granting that "North African" does not typically conjure the same image as "African American"). It seems odd to deny that America's history doesn't affect its cultural sensitivity toward certain terms (especially the term in question).
You think I'm being more charitable to the US than I am. I'm implying that white people in the US aren't hypersensitive to racial stuff, which makes "Uncle Tom's" associations all the more significant.
Discussions of racism/discrimination are different in Europe than USA. Europe doesn't quite classify people by a small amount of 'races' (like white/black/etc.), instead using local ethnicities, which can get much more complex.
