"There's also a growing presence of people who are living today as a different gender than the one they were assigned at birth. Sometimes you notice them and sometimes you don't.  (Hint: You won't know how many you aren't noticing -- that's the point.)  There are people born intersex -- with the biological features of more than one gender (and there are more of these than you might expect).  And you may have noticed this in cities and among young people -- there's also a growing presence of folks whose genders you just can't identify.  Some of them, if you ask them respectfully, will tell you they feel like both genders.  Or neither gender.  Or a gender that needs a new name.  They might answer to both "he" and "she," or they might prefer something different.  They're in-between, and that's where they belong."
