At 10 am today, the Massachusetts Supreme Court ruled that it is unconstitutional (according to their state
constitution, which prohibits the creation of "second class citizens" according to NBC news) to deny marriage to homosexual couples. This isn't just same-sex civil unions (aka domestic partnerships), as per Vermont, but actual full marriage, with all of the rights and benefits (and whatever) that entails.
So, hurrah for Mass. One down, 49 to go (not to mention the federal government, sigh).
