Right? A story is piblished for readers, in return, the readers give feedback to the story. We are not robots just consuming and not given a chance to give constructive cristicim about a piece we've read. If no one ever commented on a story, how will someone know how good the story is?? There's a reason why books has reviews and ratings even in good read.
I think there is a fine line between constructive critisism and "Dan is a wimp, let his grandmother die so he can grow some balls for my satisfaction", "Jaekyung kys, you haven't suffered enough for my liking". These are the types of comments receiving the so called "If you don't like it then leave" response.
And I think you both need to reconsider this response. For reference, all I read is "If you can't understand and see the story for what it is, if you can't decentralise yourself from the plotline and acknowledge that others will make different choices for their own journeys which aren't made to align with your preference, then this story isn't for you".
It is really dehumanising to constantly critisise a protagonist's decisions because of what you think would be best for them. You are not them. This also reflects your attitude towards real-world relationships with other people. It concerns me that people are so invested into someone else's story that they are disappointed when they don't hold any influence over their decisions. Of course, because it's their story, not yours.
The moment these people look at the protagonists for who they are and how much the unraveled events have actually affected them, rather than how much they think the events should have affected them, it will be crystal clear that both protagonists have been suffering from the start. And the suffering they are both experiencing right now is well beyond what they can handle.
Reading the comments is so frustrating yet so funny. An argument i have seen extensively is always "if you don't like it, just leave" towards people who voice their criticism, frustration or even when they bash *certain* characters. This is a comment section for a reason. I know everyone is frustrated at each others comments as well as at how the story went on so far. But cant we refrain from calling each other names or insulting each other? Cant we just enjoy the story or hate-read the story just how we want it? And if you really disagree with someone elses thoughts and comments, how about actually giving that person a change of perspective, no matter if its pro or against the story, instead of telling them to leave, cuz that way, you won't be able to make them leave at all.
