By CHARLES K. DEVALL In Kilgore ( Tex.) News Herald HOW STUPID CAN Americans be? Surely if there were ever a case of over-reaction, it is the response of many in our country to recent events in Red China. A table tennis team and a small group of reporters are invited to this blood-thirsty nation, and the crafty Commies make it appear that they have reformed and are now a decent, law-abiding nation. President Nixon seems unduly impressed and hastens to lower the trade barriers which are one of the most potent weapons in our defense. The radical left and the soft-minded bleeding hearts, as expected, are smiling from ear to ear. IN THE FIRST PLACE, was it a ‘‘Big Deal’’ when the Reds chose table tennis as a competitive sport? That's a favorite game for them in which they're the world’s best, and it certainly is not one of our major sports. The most frightening development of the week for us was the AP story from Hong Kong telling how John Tannehill, top player on the U.S. table tennis team, has fallen in love with the Reds. Now hearing his disgusting words: ‘I much prefer the Chinese system . . . I really love it.’ The 19-year-old sophomore at the Uni versity of Cincinnati said he has considered himself a Maoist for six months, saying he became interested in the philosophy of Communist Party chairman Mao Tse-tung through his experience at college and his school friends. IT WOULD BE INTERESTING to know which of his professors sold him on this godless, anti-American doctrine. Perhaps he is of the same stripe as Herbert Marcuse, the admitted Marxist who taught Angela Davis in an Ivy League university and so impressed her that she followed him to California for graduate study in a state-supported university. Now she’s on trial for furnishing the arms which caused the murder of a judge and others in a California court room. To set the record straight on this ping pong matter, Tannehill, the sociology student, is the No. 2 ranked table tennis player in the U.S. Who is No. 1? No less than Dal Joon Lee, four-time open table tennis champion of the U.S., but he’s a South Korea native who holds strong anti-Communist views, and naturally did not make the trip to the land of Mao, that paradise where the first principle of government is: ‘‘All power comes from the barrel of a gun. And it’s the dictator nation where almost every statement about Americans refers to us as ‘‘running dogs of imperialism!”’
