I tend to get more excited about country-level acceptance of same-sex marriage, because I'm so hopeful that we'll all join the civilized world in this matter.
But states matter too, in that they at least add to the momentum going on and may eventually contribute to the USA finally getting over itself and noticing that this is what people want.
So! Yesterday Rhode Island became the 10th state to adopt same-sex marriage! Woo double digits! Apparently they were the last holdout in New England, so now that whole region has come to its senses. Nice!
