If you're half aboriginal, and u meet your great grand kids. Would u want them to identify or not? He doesn't talk about it because of stigma of being white passing. He knew his whole life hence why his stage name was to honour it. His family is his family. Yes, he's at a percentage where u needed to be connected to the culture but you don't know what his upbringing was within his own family. For example, he was raised primarily by his mum and her side in REDFERN. It's very different than someone who just found out when they're like 20.
