Racism criticism is 'projection'
“Doonesbury” cartoonist G.B. Trudeau often attributes criticism of President Obama to racism rather than political disagreement. That indicates he has racist issues of his own. Psychiatrists call that “projection,” as when liberal hate-mongers falsely accuse conservatives of hating.
Obviously Trudeau is afraid his readers might suspect how he really feels about people whose skin colors differ from his. He and his fellow left-wingers hope that by supporting a half-white male president, they can keep a real black candidate such as Condoleezza Rice out of the office.
