You make a good point that I've fought with for a while too. My thinking on this is that unless I can be shown the work for what that % is supposed to be, we're just being wrong by policy, rather than wrong by systemic cultural biases.

I don't believe that a perfect world has every job populated by a even number of persons of all genders. To me, that would suggest that we believe all genders to be the same.

For example, Almost 100% of midwives in Ontario are female. Is this fundamentally wrong and needs to be addressed? What is the correct percentage of male, female, and other midwives? What is the measure of our policy's effectiveness?
