A Modesto anti-pornography group wants a local radio station to quit broadcasting the nationally syndicated "Sexually Speaking with Dr. Ruth Westheimer" talk show. "What I am concerned about is say a 12- or 13-year-old listening to it," said Harry Kullijian, president and founder of Citizens Leading Effective Action Now, or CLEAN. "How is that 12- or 13-year-old going to respond?" asked Kullijian, whose group led a crackdown on adult bookstores last year. Kullijian said he has complained to the federal Communications Commission.
