So determined to be inclusive that it forgets to be accurate or useful.
It's just so bizarre, the things that the author decides to include and the things that they decide to leave out. It's not very useful if all it does is tackle the easy part. If I bought this book hoping that it would help me explain sex to my children, I would be sorely disappointed. Because it does not do that. It provides an extremely brief overview of the biological components of making babies, and that's it. I respect their attempt to be inclusive of all genders, but their execution leads to distortion and confusion of statistically relevant facts.
