How is a demand that is easier for the childless to meet, even if only slightly, not a policy that favors the childless? That's not sleight of hand. It's just English.
Because a demand isn't a favor? A demand to someone implies a loss on their part, of time or effort or value. It doesn't matter how easy it is for them to do. If I say that ice cream vendors must give out their ice cream for free, it's not a policy that favors them just because they can more easily meet the demand then someone without an ice cream business.
You're being very slippery with different meanings of "demand" here. I have no interest in engaging with such sophistry, as I'm sure honest readers already knew what I meant.
You are being very slippery with different meanings of "policy" here. Of course, we have to engage with -- and reject -- such sophistry.
A demand is not a favor, it's not a benefit, and it's not a policy.
