Jeremy Irons is making headlines for his hesitancy on gay marriage and whether it might lead to incestuous marital relationships if only to avoid estate taxes. Irons says,

Could a father not marry his son? … It’s not incest between men. Incest is there to protect us from inbreeding, but men don’t breed… If that were so, then if I wanted to pass on my estate without death [taxes], I could marry my son and pass on my estate to him.

The interviewer was dismissive, but why not incest? Because of tax problems? Is’t that why Ms. Windsor went to the Supreme Court to begin with — taxes?Seriously. Why not incest.The left is championing what Senator Mark Kirk said last week when he decided he would support gay marriage. Senator Kirk said, “Life comes down to who you love and who loves you back — government has no place in the middle.”Shouldn’t that include committed incestuous relationships? If love and commitment are the justification for marriage, why exempt this?But … but … but what about the deformity of the kids, etc. Well, gay couples cannot have kids. Just as gay marriage advocates say the concerns about procreation are archaic when it comes to marriage, they are definitionally irrelevant if we move on to gay marriage.So why not fathers marrying sons and moms marrying daughters? Is it because of the “ick” factor? Why should that preclude it?If life comes down to who you love and who loves you back, if a father and son love each other so much they want to get married, there is little moral difference between two people of the same sex getting married who are not related and want to be and two people of the same sex who already are related becoming closer.

O wonder!
How many goodly creatures are there here!
How beauteous mankind is! O brave new world,
That has such people in’t.

The truth is, many, many, many of the same people who are now in support of gay marriage, but would oppose this or polygamy will, once the next step is advanced, support these things too. They just have to lie about it for now until they can shift public opinion further. Maybe instead we should ask them who they think is more disposable, mom or dad.
