If you're complaining that there's not enough rape, assault, paedophilia and homophobia in stories these days then you're the problem. Honestly you can still find that stuff all over the place, and there is no shortage of psychological, thriller and horror bl either, go read Blind Play. Idk what exactly it is you're even complaining about.
I am very sorry for your collection being ruined, that sucks.
But as a "new wave fujo" and an adult I disagree with your opinion. We don't dislike mature topics and only read high schoolers struggling to say daisuki.
Mature and heavy topics have go be handled correctly, that's it. You said it very correctly, ten count was popular because it has mature themes. That's why I liked it as a 13 year old.
As an adult I could recognize that the themes were handled with no care and regard for people struggling with those real issues and that it just blatantly fetishizes them.
Just because it has dark themes doesn't mean it's automatically good.
Also, nobody is asking fictional characters for apologies and while certainly there are people threatening mangakas i can assure you that I as a so called "new wave fujo" do not condone that.
Since it had been a while and I'm currently waiting for my replacement volumes to come in the mail ((had a real bad outbreak of mold in a storage area I used so 50% of my manga were ruined)) and I'm honestly not surprised by the fact that new wave "fujos" are having a normal one over it now lol
It deals with more mature topics than most series that are just centered around high schoolers struggling to say "daisuki" and it wasn't afraid to add a lil taboo spice into the mix. When it was first being serialized in jp everyone loved it 'cause of how serious the subject matters were. It was made for a more mature audience that could understand that this was a fictional setting and thus could actually enjoy it from beginning to end.
Now everyone likes to circle jerk over how "morally just" they are for consuming "safe horny" shit and suck the fun and enjoyment out of anyone who thinks differently. You've got people who spend way too much time making claims of being "fetishized" when they are literally a nobody, and others who demand fictional characters write apology letters for doing something bad lol then you've got the ones who harass mangaka or their managers and fans for writing "illegal" stuff or just something they don't like in general.
This is definitely the weakest and most pathetic generation of readers I have seen in all my 20 years of reading bl/yaoi. This genre becoming mainstream was a fucking mistake lol
