USA is staggeringly bad for Developed world and UK one of worst in Europe.
Is it partly due to sexulisation of advertising, writing, and Adultization of Teenagers?
Young Adult OUGHT to mean 18 to 28. In reality it's become a euphemism in English Speaking Developed World for Teenagers (13 to 19 or even 10 to 19).
There is a difference I think between portraying or accepting or explaining or educating about Hetrosexuality, Gay, Lesbian, BDSM etc and
promotion of them, either generally to wrong age group or in wrong way.
I don't think it's the job of Fiction writers to Educate (that becomes preaching and selling under false pretences), though fiction can incidentally be educational. But I think it shouldn't deliberately send the wrong "messages" to young people either, about violence, crime, theft, honesty, honour, respect, sex, drugs, self mutilation etc.
The primary aim is surely to entertain and give some escape from some harsher realities that some people experience. Thus as a side effect it can promote people to think about their situation instead of going along with peer pressure, consumerism / advertising pressure and also avoid destructive total despair.
This is why I think some books supposedly for YA are unhealthy. Are they even really entertaining, or does feed the dark thrill of watching a despised weakling getting bullied or an inadequate teacher getting ragged?
Are some books (that may even be successful) actually "bad" for many adult readers? I don't want censorship, or books banned from Libraries or Amazon, book stores etc, or even the Rating system used on Films and slightly on games (those often don't work, or at least need simplified and reformed, also USA, UK, Ireland rate video and films on quite different basis).
But I'm not going to write stuff that inappropriately promotes stuff, or is so dark that once the thrill of reading has worn off you feel sick or tainted. It's not just about Sex.
