What if Zimmerman was a girl? And/or African American? And what if Trayvon was "half white", as some media reports describe him? And isn't that descriptiion in and of itself an interesting topic for discussion? My guess is if any component of this story change people's narratives change with it.

Absolutely. If Zimmerman was an old lady out on neighborhood watch, it makes a difference.
