Ah but they converted so not appropriation.
Lots of Vikings converted to Islam. They were friendly traders for centuries so it’s no surprise.
Some people are proud to call themselves white trash in the US. Sort of a reverse badge of honor. “Yeah we’re white trash but we’re happy”. Stuff like that.
Examples of rich white trash would be Paris Hilton, the Kardassians (that always makes me think of star trek :DS9).
