Someone finally standing up to the intolerant left?
Well, sort of... almost. In this case.
Every culture that exists today is a fusion of elements of earlier or contemporaneous cultures which interacted to create a new hybrid. The aboriginal culture in Australia may well be the only pure culture in the planet, due solely to isolation. Accusations of cultural appropriation are simply another attempt to divide people into yet more groups for exploitation via identity politics. Anything to prevent people from seeing that what we have in common is more important than the differences being used to divide us.
