Hating on pineapple pizza.
Buying slaves or endorsing it, making justifications for it.
Not murdering the big bad guy, even though that being won't stop being the big bad guy.
Perverted without proper reasonings behind it.
Denser than a black hole.
Treating everyone beneath him because of his belief or reasons.
Not treating woman/man as a human being rather a thing to pursuit after or to sexualize at.
There is been a lot of hate about Chinese novels, are they really that bad?
Regarding Chinese Novels.
Can't say for sure how representative that is, but once I read here one with views that kinda disturbed me that was obviously from a Chinese.
The MC was telling her mother that she won't do her chores (or not yet, not sure anymore, but it wasn't too unreasonable), they get into an argument, and the mother cracks MCs head open against the wall!
Then in death's void, the daughter apologizes to her mum for being such a bad daughter.
I was looking rather awkward after this.
I guess the more aggravating things are the usual cultivation novel tropes.
One quite quickly sees how much of a wish-fulfillment self-insert the protagonist is.
The strongest trope that I repeatedly saw is a strong class system. No, not a social one, but about given abilities.
You'll never see that someone of a lower rank wins alone in a fight against an upper rank. There are different depictions of this, but it's usually "Here is the pinnacle, here is the bottom, you strive to raise your rank".
It's actually ridiculous how hard authors are throwing any semblance at logic out of the window to avoid an upper rank gets even scratched.
Surprise attack? No, the upper ranks have supernatural senses that can even warn them in their sleep.
Stray shot from the side? See above.
Poisoning? No, they of course developed poison immunity with their power.
Any kind of attack from a lower rank? No, they all have always shields or perfect spatial awareness and abilities to dodge any kind of damage.
That one fire mage even had a "heat shield" that absorbed massive stone pillars. That's not how physics works!
So yeah, a rank 3 can basically go alone over a hundred rank fours. The higher it goes the less anyone can care about the lower ranks because they are simply unable to make an impact and are quite clearly sidelined.
I recently read Sapiens. A story that started out strong but then went down with exactly this trope.
