European everyday racism feels a bit different than American racism. It's the end result of many cultures interacting over centuries and accruing generational memories of when X group screwed them over. Meaning, everyone is equally racist to one another. Also, it's not based so much on physical race, as on group belonging. For example, often people from within a single country would be prejudiced to one another, based on the specific city one is born in. Depending on how the country borders get redrawn and what the government decides to call the ethnicity of people within them, those relations can technically flip between being racist and not.
Basically, we can be casually racist with each other, because it's between equals. Americans can't, because it's between two groups, one of which used to inflict horrible human rights abuses over the other.
