To equate "right and wrong" with "true and false" by assumption would be to, well you know, beg the question.

I'm not equating moral right and wrong with true and false. I was disambiguating some ambiguous words that you employed. The word "right" is ambiguous, because in one context it can mean "morally righteous", and in another context it can mean "true". I disambiguated the words in a certain direction because of the immediate textual context. Apparently that was not what you meant. Okay - so ideally I should go back and disambiguate the words in the opposite direction. However, I can tell you right now it will come to the same result. I don't really want to belabor this point so unless you insist, I'm not actually going to write yet another comment in which I disambiguate your terms "right" and 'wrong" in the moral direction.
