Yes, Les, the Black Australians went thru the same process as the indigenous Indians on the American continent. And lots of the Aborigines kids have been deliberately "made much lighter" by the Australian federal and state government agencies. For many years those referred to as half-caste children were forced to racially mix with whites, they are known as the stolen generation. Today many of their descendants don't even look aboriginal, not one trace of Blackness on their physical being.

As for this vlogger brotha, I think he posts videos according to what his YouTube followers or fans demand from him. He generally shows what others want to see. Apparently I can see that thru his vlogging camera some ppl are seeking connections with different cultures or simply want to know about other societies and their way of life around the world.
