Because we're talking about the particular way that mothers are financially disadvantaged due to bearing and raising children in the current paradigm of how we arrange our working lives.

So no. Cisgender women who choose to not have children would NOT be included because that are already NOT being financially disadvantaged by their choice to NOT have children.

Any other configuration of woman who was not born that way but IS rearing a child, whether they birthed them or not, would also obviously be included because the idea is about raising children without it being a financial punishment, not your fucking genitals that I don't particularly care to hear about. No need to go TMI or hijack a conversation for your own agenda.

And just so it's said, since extrapolation is apparently too hard for some, I also don't have a problem with stay at home Da's getting the same option or splitting it with their partner in some way. I fully support payernal leave. Once again, the concern here is that raising children not be unduly burdensome to anyone.
