Actually, snarkiness aside, Seawytch's point if perfectly valid.
You made it clear that in your opinion two things exist:
1. The Federal Constitution ONLY applies to the Federal government,
2. That the Federal government has no right to dictate marriage laws to the states.
Under your logic then States could ban (at least through a State Constitution Amendment): interracial Civil Marriage, Interfaith Civil Marriages, they could even ban Civil Marriage to Muslims only. Why? Because the incorporation of the 14th does not exist, therefore the 1st Amendment applies only to Congress and the Federal government because the 14th Amendment does not make the Bill of Rights applicable to the States. The only "rights" then held by the people in terms of State action are those contained in the States Constitution and if the people of a State amend their Constitution they can do anything they like.
Kind of like Alabama which banned the CHOICE of people of different races getting Civilly Married. (Language which the electorate finally removed in 2000 via a new amendment vote, the sad part being that (IIRC) 40% of the vote was to retain the discriminatory language.) Each race could get Civilly Married, just not to each other.
The logic of your position is that the Federal government had no power to prevent such discrimination.
