Request for sympathy; frustrated with Dark Side

It is really quite frustrating to discuss the intersection of physics and free will with a man who is capable of posting this as his opinion:

I regard atomic motions as determined, that is, as exactly defined to an infinite degree of precision, by the laws of physics, with nothing left over or left out of the explanation, and nothing else to explain.

and then, a day later, posts this as summing up mine:

[His] axiom that the motions of atoms are determined by and only by that description of non-deliberate physical reactions to outside forces called physics. [...] This axiom is not just false, it is obviously, outrageously false.

AAAGH! *Make up your damned mind, man!*
