Jefferson? The slave owner?
Yup, that's the guy. The same guy that the SCOTUS quoted and used as precedent for the mythicla Wall of Separation.
Now do you think it possible for you to dig deep down and admit thet the Wall of Sparation theory is not located either in the Constitution or Jeffersons head?
And if it's a wall you want, why don't you amend the Constitution and put one in there.
