With stories like this, I have found it to be the opposite. People that would usually question this, won't because they are terrified of being called sexist which is (exactly what you have done and) one of those things that hangs around you and can ruin your career very quickly.

This style of marketing is becoming very popular. The young, disadvantaged, novice, whatever does something extraordinary through sheer brilliance and dedication [1][2][3] and when their claims don't really match reality [4], nobody cares. The marketing has already succeeded. It is exactly the kind of marketing that is taylor made for social media and if we don't want to be inundated with it in the future, we need to question it every time it appears so that only the truly deserving reap its benefits. Extraordinary claims (should) require extraordinary evidence.
