Same-sex unions

In an editorial today, the LAT argues there's no difference between a same-sex union and marriage. Well, one difference is the sex of the partners. Another is that a married couple ordinarily is able to procreate, something same-sex partners can't do. If that seems elemental it's because it is. It's no help to argue, for example, that women are the same as men, or that men are the same as women. They aren't. Some things are immutable.
