As long as a State issues licenses to drive or get married or own a gun or carry a gun and treats men and women, white and black, Latino and Asian or straight and gay the same then this ruling would have no effect.
That's the whole point.
The ruling just says that as long as states are issuing marriage licenses, they can't discriminate who they issue them to on the basis of sexuality.
If a state stopped issuing marriage licenses, all together, then it wouldn't be obligated to issue licenses to anyone.
Love your enemies!
