Okay, as an Orthodox Christian, I object to marriages within seven degrees of consanguinity (which we define more broadly than most, since besides being spouses, being a parent or child, being godparent or godchild, and even illicit sexual liaisons create a bond of consanguinity). Meaning, for instance, second cousins once removed are okay, but second cousins are out. So, I object.
But since Orthodox canon law isn't applied by any Western Christian confession, and is not instantiated into secular law anywhere in the US, why is this scandalous to the rest of you?
