They are more racist here, I'd say. But it's strangely intertwined with the way they talk and see the world in general. I know a guy who everyone calls "el chino" and he's not even Asian, just slight squinty-eyed. Another "el negro," "la negra," etc. (These also, not black or even native). They tend to label and then stick to it, unfortunately this can lead to even more racism.
When it comes to staring, I'd say they do stare more. I have very light blue eyes: it warrants, inevitably, stares and comments. I guess, being white, it isn't racism, but it is strange.
Sorry to all those who have had bad experiences.
