True and false are binary. "True enough" is, ummmm, false. Remember "truthiness"? Beside which, I also think the information about O'Keefe is pretty interesting (note that "interesting" is not binary, so can be qualified that way) and added to the conversation. Calling someone a pedant because he knows more than you is uninteresting.
