I try to maintain a healthy level of skepticism where possible. I don't disbelieve this kid and that wasn't my point - I was defending him- there's just a bit of a gap between "noticing you have privilege" and helping to found an organisation to help other kids do experiments. The latter claim might start to set off "too good to be true" detectors, so I'm merely saying that even if that's not 100% true the fact he's talking about it is a positive thing since some young talented people do seem utterly oblivious to their own privilege.
