Nobody is forcing anyone to watch it. Many people watch it voluntarily. If we are so sure that these media are so bad for people, why are so many people still watching it? If the answer is that these media "hack" the human brain, then I don't think that banning the producers is the right way to go. The root cause is that people are too easily tricked. Banning the producers will only cause other media, such as YouTube…

In a liberal society we allow things we don't like in order to maintain individual freedom as a higher good than "perfect" society.
Those who do envision "perfect" society and pursue it with the power of the state are the worst sort of authoritarians, because it's all done "for your own good", no matter what you think.
