Only you could come to such a conclusion.
Since dawn of air combat, differences between number of victories claimed by pilots and number of confirmed victories were common for various reasons.
Do you really think all the record keepers, military officials, historians, researcher and history enthusiasts were trying to prove pilots to be "dedicated" liars? Do you?
Another thing. If you're convinced that MiloMorai and I are calling Mr. Williams a "dedicated" liar, than grow a pair and call us out directly. Or, if you're sticking with vague hints at who that may be, then show the same moderation with your pompous phrases such as "honest individual" or a dedicated liar".

He made a statement just as you did. He did not point it at anyone. You spoke up about his statement... does that mean you feel some guilt?
Either everyone can make statements or no one can.
