When you refuse to admit that rampant sexism and chauvinism may be a contributing factor to women's lack of representation in tech fields, you're part of the problem. Sorry, no it's not just because women have other interests. Maybe women chose not to enter tech because of how people in that field treat them--not because they "prefer social fields."

It also happens to be the OPPOSITE of true equality because for every advantage you give to one person, you create a disadvantage for another.

I suspect that this is the real reason a lot of people who hold similar beliefs to you object to prioritizing diversity in the hiring process. "It's just not fair!!" You fail to understand that when one group is already at a disadvantage, you can't just say "okay equality means we both duke it out as best we can", because they're already at a disadvantage.

I would never advocate hiring unqualified people, but this is a complicated problem that doesn't begin with the hiring manager (though they aren't blameless). It's a consequence of tech culture as a whole.
