No it isn't.
The 1996 Defense of Marriage Act was passed BECAUSE this is a federal issue.
Federal IMMIGRATION, TAXATION, INHERITANCE, and FULL FAITH AND CREDIT.
Covering your ears and going “la la la” is not going to change the FACTS OF LAW.
There are right now, FEDERAL lawsuits for test cases on forcing this into Full Faith and Credit on immigration and taxation.
Saying otherwise is only playing into the hands of the homosexual advocates. Sticking you head in the sand on this issue will only leave you exposed in the wrong way.
