I hate people like you a lot. You're literally doing the exact thing you're accusing others of doing, expressing their thoughts on something. You have no right to tell people what to do. They read it, and whether they choose to vent about it is up to them.
"Don't like it, don't read it" is such a lame way of condoning bad things. It's like saying, "I like rape. If you don't like it, shut up and stop talking about it."
Do you realize its insect that you're reading? Do you expect it be sunshine and rainbows? Please notice that the universe granted you the freedom to choose and that includes if you're reading something that stressing, disgusting or upsetting you, you, by all means, can stop reading it instead of complaining

Do yall notice you have the option not to read it instead of complaining each chapter about how fucked up this story is?
