"Sick Lit Books Aimed at Children"- summary

The Daily Mail article "Sick Lit Books Aimed at Children", by Tanith Carey, presents the idea that YA books about darker issues are not good for teenagers. Ms. Carey presents her idea by paraphrasing the plots of several books that deal with "the harsh realities of terminal illness, depression, and death"- namely, The Fault In Our Stars, Never Eighteen, and Before I Die. She continues by talking about books that deal with suicide; specifically how there are entire books on the subject when other forms of media will gloss over it "for fear of encouraging copycat behavior".  She calls such books "morbid" and "mawkish", saying that using teenagers with severe situations to build dramatic tension is "distasteful". She concludes with a quote from a child psychologist: "Let's hope publishers do have young people's interests at heart- and they are not selling books by sensationalizing children's suffering."
Ms. Carey uses many craft moves to convey her ideas. Her tone is disdainful towards these books and their publishers- she uses loaded words such as "disdainful", "morbid", "exploitative", and "questionable". She quotes psychologists who agree with her opinion, while also addressing the counterclaim with quotes from others who have opposing views on the subject. She urges parents to check up on their children's reading habits; her tone is sympathetic towards them.
While her article is well-written, I disagree with her. I think it's important for young adults to read books addressing darker themes. Things such as death and illness are part of life, and it's easier to connect with a protagonist who is going through the same troubles. Reading about subjects such as suicidal depression and self-harm doesn't encourage the reader to start cutting...which is why the term 'sick-lit' stood out to me. Is everything not about vampires and supernatural stuff unhealthy for teens?
