The difference is that Brazil was a slave state were the slaves and local populations became the dominant culture. In the US, white settlers persecuted everyone that wasnt a white English/German protestant. Catholics were ostracized to the point where an entire colony was established to keep them. Millions of native people were slaughtered and their cultural identity stripped and suppressed. Africans taken from their homelands to be sold as property had their entire identity stripped from them while they worked the fields as slaves and denied their own culture. After "liberation" they were still second class citizens who lacked equal rights and had their interests and culutre viewed as lesser. Now those cultural elements have been commercialized, but it's the descendants of the oppressors who profit, not the oppressed. Irish Catholics would be enraged and protest if London had a soccer team called "The Wimbledon Mickeys" or if the RUC did a river dance before official events.

The US is a multicultural state, but that is despite the best efforts of oir leaders, not because of them. I've met plenty of people who scream 'Build the Wall!" and call Mexicans all sorts of slurs, but are then happy to get blackout drunk on Corona and margaritas at a Mexican restaurant on Cinco De Mayo. Jazz music and the blues were forbidden from radio stations because they were associated with black communities, but suddenly white people started to incorporate elements of the blues into music, creating the mosern rockstar. And while Mic Jagger, Elvis Presley, and Steven Tyler are household names, Duke Ellington, Louis Armstrong, and Muddy Waters are relagted to music history classes.
