People in general don't talk about America because they want to be Americans. Some of them do it because they are worried about the effect that it could have in the rest of the world. Others because they have empathy about people suffering under the government (local or foreign). Others just because it's entertaining and sometimes stranger than fiction, like somebody that watches Netflix.
I'm so sorry that your circle isn't worried about what's happening around them. I'm happily surrounded by young and middle aged people that cares about their neighborhood, city, and national politics. I'd prefer that they didn't have to worry because everything was perfect, but this is what we have, and I'm happy that near me there's people with empathy and solidarity feelings.
