From the article:
"Vietnam’s Ministry of Information and Communication is concerned about the popularity of ‘oversentimental sex fiction of Chinese origin’ among young Vietnamese people and is trying to stop the pulp novels’ sale and publication in the country. - See more at: http://www.gaystarnews.com/article/vietnam-being-flooded-gay-chinese-pulp-erotic-novels170415#sthash.4sfXVuhb.dpuf"
If "over sentimental" means romantic, perhaps that part of it is actually constructive; it indicates that gay persons are capable of having emotional and romantic relationships. As for the "graphic" descriptions of irresponsible behavior that the article also mentions, that is another matter.
