In my view, they should be banned. These novels can have a bad influence on the psychological development of people. They can distort people's understanding of sex and love, and may also lead to some people having abnormal sexual concepts. By banning them, we can create a healthier cultural environment.
Yes, they should be. Given their potential to corrupt minds and violate moral standards, banning them can protect the public, especially the vulnerable ones like children and adolescents.
