I don't use stuff from that continent (in fact, as far as I know, Kbin is European, and lemmy.world is even based in Europe). But when I browse through all, majority of content is related to US somehow, and majority of comments are related to something in the US too.
I can block communities and instances, obviously, but generic communities are being pushed to US culture somehow, despite having allegedly users from other countries and continents. And there is no filter, unfortunately, so either block or get bombarded by US-related stuff
