It's introduction and parallel with sex means the article makes a wider point about a difference between sex and gender. I agree this article could have been written better without any mention of gender so as to avoid making an out of scope claim in a pop sci article.

Where does it mention locker rooms or "the trans community is the strongest supporter of traditional gender roles?" Did you read the article?

I didn't, stop paraphrasing me, it's lazy and harmful to actual discussion. I pointed out why it's irrelevant.

You asked a pointed question.
