"The Founders demonstrably disagreed...they made such tests illegal."
They didn't grant the power to impose such tests to the federal government, reserving them instead to the states.
Wow.
That's profoundly ignorant.
Article VI, Clause 3:
The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.
Very clear.
You may wish to try reading the Constitution sometime - you'll be amazed at what's in this amazing document.
"In 1777 most states passed Test Acts. They required everyone to take an oath of allegiance promising to defend the revolutionary cause with arms. Pennsylvania law decreed banishment and confiscation of all property for those who refused the oath."
Game. Set. Match.
