Article: natural sex hormones influence gender based behaviour, and different species with different genes react slightly differently to that natural hormon.
Social justice warrior blog, err, boingboing: gender is 50% culturally constructed!!!1!
I can't entirely blame you though. The article contains a complete non sequitur: "a child chooses to engage in certain behaviors may be determined less by sex than the biological environment they are exposed to."
As far as I know, testosterone is not "part of the environmnent"* It's an hormon, but not a pheromon.
* except in the womb where they mention there's more of it if the mother is stressed, but that has nothing to do with nurture anyway, plus the article is about the comparative level of testosterone long after birth (look at the graphs).
