Software update

Youth doesn't think in terms of a rigid binary so those stuck with the old mindset need to update their software. They see the divergence from old rigid norms as entirely expected. 

In other words, youth isn't on the lookout for perfect archetypes of man and woman.

It tends to throw the concept of "passing" off kilter a bit since they are more aiming for originality and authenticity. 

I see it everyday.
