The defense of lack of jurisdiction over the person may be joined with the other defenses in Rule 12(b) since under the express language of Rule 12(b), “ ‘no defense’ [in Rule 12(b)] is waived by being joined with one or more other defenses in a responsive ... motion.” See Housing Auth. of City of Atlanta, Ga. v.
