A lot of Euro comics were super racist. Tintin had some extremely racist early issues but later they became better. I remember there was a later issue where Tintin actually helps a revolutionary character who seems to be some kind of Castro/Che analogue, although in the end it seems to kinda do the liberal "they're all the same anyways" in the end. Asterix wasn't always exactly racist but like half of the humour came from stereotypes. Usually it was just stuff like Viking dogs barking in Nordic script, Egyptians speaking in hieroglyphs, British having massive teeth and taking breaks from battles to drink tea, Swiss being neutral and obsessed with keeping time very accurately, some self deprecating stuff about how French become very angry about past losses and pretend like they didn't happen, and other stuff that doesn't age that badly. But then there was stuff that did age poorly, like the way they drew black people. But in the end everyone except the Romans ended up being "good". Generally I think Asterix was the best out of the popular euro comics, there were much worse both in terms of quality and racism.

The most recent Asterix movie though was extremely uncomfortable, they had a character that was clearly supposed to be some kind of Pakistani immigrant/refugee and the portrayal was super racist, especially in context.
