In the US, even without "gay" "marriage" from sea to shining sea, we're already at the tipping point: over half the births to women under the age of 30 are already out of wedlock.
Since marriage by any definition is no longer the norm, does that mean the government must now carry through with the far more expensive, and far more intrusive, policy of administering DNA tests to all of a woman's ... er... male associates, upon the birth of every child?
Or, drawing back from that, do we just say, "OK, every child is now a half-orphan: a paternally abandoned child. We've given up. First, no more legal wedlock. And now, inevitably: no more legally enforceable children's rights."
This is not a trick question. I'm asking.
Short answer: Yes, the government must now bear the expensive burden of determining paternity in situations where the mother and (alleged) father disagree.
I know it stinks, but that’s the way it is.
But it still has nothing to do with marriage.
