There was a moment in college when I was participating in a Take Back the Night march, and I was leading the call-and-response chant "What do we want? Safety! When do we want it? Now!" It felt awkward and wrong. Once I stopped leading the chant and started participating vigorously in the response of the call-and-response, it felt right.
Maybe your sentiment can be enhanced by not gatekeeping participation - but by promoing a handover of leadership to more symbolic choices once the work of buuilding momentum is done. This is a rule that could be applied to any demographic-based leadership that needs to organize its aesthetic as it grows
But there is no substitute for the underrepresented assuming actual positions of real power and leadership — breaking through ceilings, becoming role models, making mistakes and overcoming them... and eventually becoming ordinary and routine.
