Someone whose gender identity (their internal sense of being a man, woman, or something outside that binary) differs from the gender they were assumed to be at birth.
Someone whose behavior or appearance does not conform to prevailing cultural and social expectations about what is appropriate to their gender.
A gender identity other than male or female. Some nonbinary people use “they” or another gender-neutral pronoun rather than “he” or “she.” Recently enacted laws in California allow people to select “X” rather than “M” or “F” as the gender marker on their formal identification.
