Only the tradional marriage should be legal. Right? If you think that's the union between one man and one woman who make their pledge in church you are very wrong. Traditionally there are many forms of marriage. Take the Bible and see the examples of men being married to dozens and sometimes hundred's (Salomon!) of women! Most men in the Old Testament had (at least) two wives. So does that mean that that is normal and traditional? Or take the scientific fact that about 0,5 percent of all people is neither a man, nor a woman by birth.
