It turns out there were (at least) two other pieces of good news yesterday, in addition to it being Dr. Seuss's birthday: it was Jenn and Kenny's second anniversary, and (unrelatedly, as far as I know) Multnomah County, Oregon, decided to start issuing same-sex marriage licenses.
For those unfamiliar with Oregon, that's the county Portland is in. (It would almost have to be; there are a couple areas of Oregon that are very liberal, but most of rural Oregon is, I gather, extremely conservative.)
In addition to that first article (linked above), Portland Communique features a bunch of later articles on the subject. All sorts of interesting stuff. Not clear exactly when they'll start issuing licenses, or whether they'll be stopped before it comes to that.
According to a KATU News article, "Oregon's marriage law states that marriage is a civil contract entered by males who are at least 17 years old and females who are at least 17 years old." (That article, btw, has yet another scientifically meaningless Internet poll on the subject, in which those who approve of the county's new plan outnumber those who don't, 52% to 48%.) . . . Aha; it turns out that's almost a direct quote from Oregon state law:
106.010 Marriage as civil contract; age of parties. Marriage is a civil contract entered into in person by males at least 17 years of age and females at least 17 years of age, who are otherwise capable, and solemnized in accordance with ORS 106.150.
(I suppose one could argue that the "and" means there must be both males and females involved—but at that level of detail, the plurals would suggest there must be more than one of each involved.)
106.020 lists marriages that are prohibited; the only two kinds listed are those in which either of the participants is already married, and those in which the couple are close blood relatives.
Thanks to Jay L. and Heather W. for the info!
