A bunch of uncited op-ed pieces (at least one from the same HuffPost/AEI author) is not the same as proof. You've demonstrated only that it's widely disputed by a bunch of op-eds (which you can also say about climate change, evolution, and the round-Earth theory). Going through the list:
Opinion. Mises.org lol. Opinion (and UK). Opinion. "Statistics are wrong". AEI opinion. Opinion. Not sure why you included the billmoyers.com piece, it argues the gap exists. Opinion. Opinion.
You're digging your hole deeper here. C'mon, we're not talking about income disparity in India. That study has a 200 person sample size in two Indian states.
Every year on Equal Pay Day, while some Americans lament the fact that in 2014 women still earn around 20 percent less than men, others perform intellectual gymnastics to deny that a gender pay gap exists, or to blame women themselves — and the “choices” they make — for its persistence.

As Pamela Coukos, a senior program advisor at the Department of Labor, wrote in 2012, “studies consistently conclude that discrimination is the best explanation of the remaining difference in pay.”
Pamela Coukos, June 7, 2012 has also said "Economists generally attribute about 40% of the pay gap to discrimination – making about 60% explained by differences between workers or their jobs"
Personally, It sounds like she's being a bit disingenuous.
