@srdceleva Those “European friends” are still a minority and I bet most of them are western Europeans. But regular people on the streets generally don’t study their roots. Sure, they become interested in it when you ask them, but until then they don’t think about it.
I believe in America the idea of studying your ancestry comes to your mind more naturally, since people there know that they have roots somewhere on the other side of the planet.
I mean, go and ask a few Europeans if they know their ancestors, where they come from and if they’re interested in it.
Probably most of them will tell you: “Good idea! I’ve never thought about it. I should ask my parents.”
And then do the same with Americans. Most of them will be like: “Yea, I’ve always wondered about it. I should check that out.”
