Penumbras are free-kill zones invented by liberals for the purpose of protecting death cultists who wish to destroy innocent human life without consequence.
Penumbras arise from blocking the greater light of the Constitution which exists for the porpose of protecting innocent human life. Indeed, at its broadest scale the Constitution has no other purpose.
Sometimes the lack of education about our system of government shocks me. You could not be more wrong. The United States Constitution is a compact between the states and the federal government they created. The Constitution spells out the type of federal government, the method of electing its officers, its powers, and its relationship to the states, and through the states, to the people.
