"I would try to ascertain on what grounds it was concluded that Obama is a Liar."

            That's not hard to do. Joe Wilson is not a racist. "Racist" is a word that nonthinking people use to cut off debate because they're lazy.

            When Obama said the healthcare plan he supported would not cover illegal aliens, he knew that there were no enforcement measures in the proposed legislation, so that the minute it was passed illegal aliens could line up for healthcare, like they do for most everything else, and there would be no effort to prevent them from receiving it.
