Maybe one way to get rid of those topics is to state clearly in the disclaimer that no Chinese-political-related topics-allowed in this forum, if Sailor is willing to do so. By so doing these talks will be able to be filtered as soon as they appear. Otherwise, people still talk and debates still go on. Diversity IS the nature of human community and you can not deny that. You want only FB. He wants the so-called politics and I want both.
