GP is talking about parity between maternity and paternity leave. Citing statistics about the existence (or, as is demonstrably more common, non-existence) of maternity leave is pretty orthogonal to that.
Unless you're claiming that the fact that most states don't offer any paid maternity leave (and almost certainly no paid paternity leave, either) counts as the kind of parity the GP was arguing for, I guess.

Not when talking about the US, otherwise it wouldn't just be two countries, since many -if not most- countries in the world don't have any paternity leave at all (even in Western Europe - see Switzerland).
It's very encouraging to see some states have it, but an awful lot of that map is blank... I did see a news article recently about the Navy being quite progressive in this regard though (recently tripling its maternity leave time), which is also encouraging.
