I guess it is a consequence of the Reddit migration where the habit is just keeping the old community name. But having C/Politics being US only on Lemmy.world, an instance that aims to be international (hence the name), seems weird to me.
Would have been cool to give up this assumption that everything is related to US by default when moving away from Reddit. I mean, even the canadian political news of Lemmy.ca is CanadaPolitics.
You can stay if you learn other worldly dialects. Repeat after me: Cunt. Bloody Yanks. Fa- (ok maybe not that one). Guten Tag.
