No need to rewrite Scripture; we need the sheep story for all those who identity with it.  
However, Sister Michele Morek, OSU had some good things to say about the goats in her Global Sisters article, "What about the goats?"  http://www.globalsistersreport.org/blog/gsr-today/spirituality/what-about-goats-46566.  A good read for those who don't identify with sheep.
