I mean, I’m a gay dad, so I get that what you are saying is a real problem, but I don’t think it’s a problem in this thread. If you had a goal of improving women’s ability to participate in the workforce you’d likely come up with a policy like this (that would also help some dads too, even if that weren’t the primary goal).

Women are far more likely to be the primary, stay at home caregiver if one exists and face a lot of discrimination in the workforce as a result of those expectations (on top of already facing other workplace discrimination issues).
