And the Constitution empowers the Congress to set exceptions to areas of review by the Supreme Court. Furthermore, nothing in Marbury v. Madison says that juries cannot examine and use as criteria their own judgement about the constitutionality of laws. If so, surely you could point it out. In fact, John Jay, first Cheif Justice of the USSC wrote in the decision Georgia v. Brailsford, "The jury has a right to judge both the law as well as the fact in controversy."
If you weren't aware of this, that's fine, no one could or should expect omniscience in their fellow man. But to deny this upon learning of it is to deliberately maintain ignorance in the face of evidence, ergo you are unreasonable. I won't bother trying to reason with you anymore.
You're not reasoning; you're stamping your feet.
