Of course it's an issue. The usurptation of powers granted to the people and their legislators by the judiciary is the source of much of the animus and angst of the people on both sides of the political spectrum.
When a court in Massachusetts decides, by a one vote majority, decides to make new law in direct contravention of the Mass constitution that will effect every other state in the union, then those judges have made that issue a national issue.
Amending the constitution is, by definition constitutional and it has the added feature of incorporating a republican form of government. I would prefer that amendment to simply state that marriage is not the purview of the courts but of the people and the states.
However, the Massachusetts constitution has a provision stating exactly that and it didn't stop their star chamber from making new law. So, while I don't think amending the Constitution declaring marriage is the union of one man and one woman is the best way to go, I understand those that think it is the only way to go.
The only branch of government that is weilding a tyrannical stick is the judiciary and they need reining in. Now.
The War on Drugs, gun laws and other abuses of the Commerce Clause were passed by the legislative branch and signed by the executive branch. Add to that the massive abuse by departments of the executive branch. The judicial is only one of our problems, but you consider it the only problem because it is the one most often used by the social liberals. You don't seem to consider the legislative and executive abuses a problem when you agree with their goals.
If you want the states and the people to have rights free of the federal government, it must be all rights, not just those you like. Otherwise it is inconsistent and hypocritical.
