When I was pregnant, this internet nerd was totally into the pregnancy/parenting communities. I was so annoyed when people started talking about their babies' "gender". "Gender-reveal" parties. What "gender" is your child? Are you going to find out their "gender" via ultrasound, or wait until they're born?
I was like, what decade are you people living in? I've know the difference between sex and gender since I was a child. Apparently "gender" is still "the less offensive term for s-e-x" in some parts of the country.
