This wasn't passed by the people of RI, but by the Democrat controlled legislature. Homosexual marriage was forced on the people of MA by the Supreme Judicial Court, and the Democrat controlled legislature refused the people of the Commonwealth the ability to vote on the issue.
In the vast majority of instances, voters haven't made the choice, it's been forced on them by their 'representatives', or the courts.
I disagree, voters of RI clearly want this, for they elected the legislators, probably over and over again.
You may have a point about the courts, but elected legislatures are normally the way we make laws in this country. There were no public referenda on enacting the income tax, declaring war on Japan in World War II, making marijuana illegal or making no-fault divorce legal.
