There are those cases where male and female biology differ and thus tend fall under different laws - pregnancy, abortion, nursing, issues relating to menstruation and passive birth control. Women tend to get the short end of the stick as a result; when there is no clear standard for
exact equality, equity issues have room to abound, and differences of opinion on what constitutes fairness can be challenging to resolve. There is also the issue of persons who do not fall into either male or female categories, and thus have even very basic privileges denied them. Or otherwise cis-men who by preference or necessity adopt a "female" role such as single parenting or having sex with other men, and are not adequately supported or defended by the law as a result. I would say we still have some institutional gender issues to consider.
I note that in the US
*, for one, state governments have consistently and for nearly a century now
refused to ratify an amendment to the constitution that would clearly set a standard for equity between genders, giving a lot of latitude for differences between state policies as a result. One can live in "the West" without necessarily having all the rights one would have in, say, Sweden. Federally, citizens have equal
protection under existing
federal laws, but they don't necessarily have equal
rights. In Ohio, for instance, a man can very likely drug and rape his wife without consequence, as marital rape is outlawed but not clearly defined under the law in that state, leaving an accidental exemption in cases where violence wasn't threatened. Attempts to resolve this issue in Columbus have been
slow.
Indeed, on certain issues, as noted above, it might in practice be very challenging to define equality in certain situations, regardless of the formal position of the law.
There are also situations where the law is complicated to enforce even if it is technically in existence. So for instance, women who are undocumented have few guaranteed rights in the US, even if they were forcefully abducted or otherwise did not personally consent to cross the border with their husband, or "husband". This is especially true where the husband is a citizen and she is not. So the law does not hesitate to, for instance, ignore what would otherwise be a clear right to the custody of her children if she leaves the marriage or is deported.
Finally, it is also obviously true that legal equality does not necessarily cause social equity to spring into being. One can only really prosecute crimes through the law, not reward pro-social behavior in any meaningful way.
*apologies for implicit nationalism in this posting; I am not as familiar with legal issues outside of my own country, and it is challenging to generalize between US and European laws even where one is better informed.
