Re “Re “California legally recognizes third gender option” (sacbee.com, Oct. 16): I must have missed something in my anatomy or physiology classes when I received my degree in nursing from Indiana University. I must have missed part of my state boards test of three days to become a registered nurse. I must have missed a class when I completed a lifetime credential to be a school nurse. The class I must have missed? Binary Politics. But I don't believe that is a science. Maybe it was in a political science class. Only in California.
