Let's think about whether all acts of Congress deserve our respect and obedience. Suppose Congress enacted a law – and the Supreme Court ruled it constitutional – requiring American families to attend church services at least three times a month. Should we obey such a law? Suppose Congress, acting under the Constitution's commerce clause, enacted a law requiring motorists to get eight hours of sleep before driving on interstate highways. Its justification might be that drowsy motorists risk highway accidents and accidents affect interstate commerce. Suppose you were a jury member during the 1850s and a free person were on trial for assisting a runaway slave, in clear violation of the Fugitive Slave Act. Would you vote to convict and punish?
A moral person would find each one of those laws either morally repugnant or to be a clear violation of our Constitution. You say, "Williams, you're wrong this time. In 1859, in Ableman v. Booth, the U.S. Supreme Court ruled the Fugitive Slave Act of 1850 constitutional." That court decision, as well as some others in our past, makes my case. Moral people can't rely solely on the courts to establish what's right or wrong. Slavery is immoral; therefore, any laws that support slavery are also immoral. In the words of Thomas Jefferson, "to consider the judges as the ultimate arbiters of all constitutional questions (is) a very dangerous doctrine indeed, and one which would place us under the despotism of an oligarchy."
