Barrack Obama's View of the Old Testament

The New York Times issues an article suggesting that homeschoolers may not be adequately monitored by government agencies, based upon the number of murders committed by homeschooling moms. Then, Kevin Swanson contrasts this with the percentage of public schooling moms who murder their children, and finds that the rate is 28 times higher there. In order to warrant the increased regulations the NY Times feels is necessary for homeschooling, we will just have to see a sharp increase in the murder rate among homeschooling moms.

Meanwhile Barrack Obama gives a biblical basis for his liberal agenda in his tome, 'Audacity of Hope.' Kevin Swanson interacts with his disposal of Old Testament law as irrelevant.

Does God have a right to call one of His OT laws irrelevant, do seminary professors at Dallas Theological Seminary have a right to call a law irrelevant, or does Barrack Obama have the right to call a law irrelevant?
