It's a political 3rd rail. There are laws about discrimination based on sex in the US, but you generally get a lot of flack for pointing out the unfairness if it benefits women, which is mostly considered ok since it's making up for the many years that the discrimination went the other way (and I'm actually ok with that).

And to be fair, it's a hell of a lot harder on a birth mother than anyone else. You'll notice adoptive mothers in this policy only get the 12 week benefit too, so this one is already fairer than most.

Your use of "unfairness" sticks out to me, considering you go on to say you're OK with it. Are you actually OK with the disparity or do you think it's unfairness? Can't really be both.

Unfair can simply mean not the same. Dunno about GP but this is a pretty popular sentiment. Look at e.g. GitHub saying they won't consider racial or sexist behaviour, depending on who is the offender. Look at recent popular protests in the US, where leaders organize people on skin colour.
