civil unions and marriage are not the same thing.
if you have two names for the same contract, then there is something different or you would have one name for the same contract.
the agrument that one is just like the other is wrong. can opposite-sex couples form civil union? if yes, then can same-sex couples get married? it is more than a matter of interchangable term.
there should be one contract with same rights and responsibilities.
it is the more just, the more exact and the more efficient thing to do.
not as a matter of faith, but as a matter of fairness!
thats a good point i didnt really look at it that way.
