Now the teachers' union has sent a map to gender diversity in cultures around the world. It's by PBS if you care to search it up.

"Terms such as transgender and gay are strictly new constructs that assume three things: that there are only two sexes (male/female), as many as two sexualities (gay/straight), and only two genders (man/woman).”

I don't know where to start with this sentence.
