You claim that, but I've seen research that shows that even when a company actively tries to hire more women, they still subconsciously give men preferential treatment, simply because they look the part.
Blind hiring studies tend to disprove that, at least in the tech industry.
When you remove all indicators of gender companies hire fewer women, which means knowing that a candidate is a woman results in higher likelihood to hire than not knowing gender.
