Criticisms from democratic personages can be of only two kinds, those that are wrong and those that are not. Criticisms that are not wrong can help remedy our shortcomings while wrong ones must be refuted. As for such types as Liang Shu-ming, Peng Yi-hu and Chang Nai-chi, if they want to fart, let them. That will be to our advantage, for everybody can judge whether the smell is good or foul, and through discussion the majority can be won over and these types isolated.
