Come on. You can take issue with the methodology of the study, but at least have a little basic respect.

Essentially the conclusion was that not everything can be explained through simply dividing by hours worked,

Which is exactly what you'd expect if there were a pay gap.

but there are a variety of possible explanations including both discrimination, career choice and work/family balance.

Fair enough, there are multiple causes. But if you look at the factors they account for (and which therefore fail to explain the missing 20 cents on the dollar, see pages 2 and 9), many of them are closely tied to work/family balance and career choices: experience, occupation, marital status, hours worked per year, etc. Few, if any, are proxies for discrimination or other social phenomena out of any particular woman's immediate control.
