Where you come down in this debate, I think that it's inarguable that there was contention and controversy with respect to incorporation even in the infancy of the Republic, and not just in the judiciary but in the respective state legislatures as well.

Not in infancy -- but in toddlerhood, once it was obvious that the new Federal form was working.
