In American Christianity, there is a minority who believes this country belongs to them, and that they are entitled to re-write its laws to fit their interpretation of Holy Scripture. They are called Dominionsts. They have no power, but they are very loud in their opinions. Other aggressive people believe that their rights as Christians trump anyone else's rights as Americans, rights enumerated and guaranteed in America's Constitution. The trouble with these viewpoints is that America's government is secular, not religious, and our rights as citizens are paramount.
Some on the Right believe that to oppose the thinking of this minority of Christians -- that they should be able to essentially control the country and that their rights trump everyone else's -- is the same thing as rejecting religion in general or the Christian faith in particular.
They are quite mistaken.
