Supporters of the ballot initiative argue that same-sex marriage erodes heterosexual marriage, but experience has proven them wrong: Since Massachusetts legalized gay marriage five years ago, the state has seen its divorce rate, already the lowest in the nation, decline further. But that hasn't stopped supporters of the initiative from making other wild claims. No, gay marriage is not being taught, alongside spelling and long division, as part of the public-school curriculum in Massachusetts. No, an equal right to civil marriage has not rendered Massachusetts genderless.
