is there any things manga incorrectly taught you that you've changed ur mind on?

i was thinking isn't the issue with how toxic themes such as abuse etc are portrayed in manga due to how manga may romanticize these issues- instead of tackling them properly?
sometimes i wonder if authors themselves normalize the issues.

i othink the issue with toxic themes in fiction lies not in the fact that they exist (fiction is the no.1 best place to explore toxicity in my opinion) but the problem lies in the authors not really looking at the problems properly.

for adults, this may be okay because they can form their own judgments like 'why is this manga trying to justify this crap?'

but the issue comes when super young people read it and then think that this is the way life should be.

((Like how i used to think that being in a relationship with a dangerous oresama type was hot when i was a teen (there's so many of them LMAO)
but then now as an adult i see that sadist/masochist relationships are actually NOTHING like the abusive oresama; in fact it's all about making an agreement on how to treat each other.))

what do you think? have you got any examples of incorrect lessons you learnt from manga as a younger person that you've changed your opinion on?
