What I believe should happen? Option 1. What I think would happen? Option 2.
Option 1 would rape states rights, while Option 2 allows gay marriage to slowly insert itself across the country state by state.
Equal rights trump states rights.
While I believe in equal protection under the law, states rights trump and natural law trumps states rights. In other words option 2. The Federal government has NO right to encroach upon this most personal of human matters. The states will ban it. Even the ones who the judges have forced it upon the people against the will of the people (California). Indiana's soon coming ban will be upheld.
