Continuing the Republican crusade to make gay and lesbian people second-class citizens, the Governor of Massachusetts, Mitt Romney, has successfully invoked a 1913 state statute preventing out-of-state couples to wed in Massachusetts. Romney hates homosexuals so much that he acted even though such marriages would be only symbolic, given that no other state recognizes same-sex marriage.
I think there's a strong connection between the mindset which opposes same-sex marriage now and that which opposed interracial marriage in the 20th century. In the Massachusetts case, that connection is starkly clear:
Legal experts have said the  law was passed to prevent interracial couples from getting married.
Racists and homophobes suffer from the same kinds of fears, offer virtually identical justifications - don't call them arguments - and in this case, use the same tools. I hope work to repeal this statute is already underway in the Massachusetts legislature.
