We are talking cross-purposes (as usual).
I didn't write that one should takeoff with any ice on the wings or the elevator.
I was referring to the hull (the cockpit exterior, etc).
My other comments on how much ice a PA28 could perhaps carry refer to in-flight icing, and decisions based on that.
I will leave this discussion now, because like I said it is like arguing against CRB checks on PE teachers.
