Sex and reproduction used to be the same

Teachers are being encouraged to use a ‘gender snowperson’ drawing in sex education classes.
Yes, really.
Teacher2Teacher, a resource community which provides lesson plans and other tools for educators, tweeted the image with the words “Using this “gender snowperson,” learn about identity and language!”
They tagged Johnny Cole as the source of the image, a “diversity” officer for Lexington Public Schools.
The image shows a gender ambiguous ‘snowperson’ and is accompanied by post-it notes, including one that reads, “Gender Identity – Girl, Boy, Both or Neither – who you are and how you feel as a person.”

I can see a graduate of genderless sex class may have a problem with college biology.
