Yep, ther are many nuances of racism even within Europe or Asia. Differences between peoples of the same continent where some are in a more privileged position due to geography, luck, history or trends and exploit others. But I would argue that in the example.you have given the xenophobia of the Black guy being a pain can’t be counted as racism as it was not systemic and was not based on a prolonged history of exploitation of white refugee. Just bc he had an individual.power or influence, doesn’t mean he was perpetuating systemic racism.
