As a Canadian woman in Silicon Valley, the biggest issue that wasn't addressed is that you're not following the money, Ms. Soh.  Isn't it interesting that while white males are more adept at science,  it is also factually true that science pays more than other jobs like care giving, teaching, and basketball playing.  Think about it next time you get your paycheck that's 60 cents to your male counterpart's dollar.  Your "factual data" is flawed.
