I have to agree with A Squared. Lyman, you're talking about a phenomenon that is separate and more involved than what was being discussed. The simple, and correct, answer to what was being discussed is that an asymmetric wing will produce positive lift at zero AoA. How the wing is held at zero AoA is not relevant.
Just to be clear - the discussion so far seems to be discussing the geometric AoA, which is in reference to the chord line. The zero lift AoA is the geometric AoA required for a lift coefficient of zero. Absolute AoA is the geometric AoA minus the zero lift AoA - any airfoil, symmetrical or not, will produce zero lift at zero absolute AoA.
The zero lift AoA of an asymmetric airfoil will be negative. The zero lift AoA of an asymmetric airfoil will be zero.
