But the one explanation I've found most concurrent is that those that hate it self insert as the main character being cucked thus they feel what that character feels. Whereas those that don't don't self identify as that character and treat it like a story they are reading with characters external to themselves.
identifying with mc only explains not caring for ntr. it doesn't explain the rage towards the genre and anybody who likes it. like for me ntr is the last thing I like, but I couldn't care less that others like it. why would it matter to me.
rage is usually a sign of fear and an attempt to mask or control that fear. like homophobes get angry because they feel something while looking at and thinking about hot guys, which they for one reason or another think is the end of the world. so rather than accept their gay feelings they attack what's causing those feelings. where as for actually straight people it's irrelevant whether someone is gay. like good for them, more pussy for me.
soo, when some people get that ragegasm about ntr, maybe they DO feel tingling in their dicks while looking at it? and because they have a delusional ideas of what a 'real man is', they're scared of not fulfilling that male model and instead get angry. like you ALWAYS see tons of demeaning language used by the angry guys, it's all 'spineless', 'weak', 'cucks' etc, in an obvious attempt to attack the manliness of ntr lovers. just like homophobes beat up gays.
and of course the subset of ntr lovers who berate other people are no different. they're just as likely to try to attack the 'manliness' of others because they too haven't dealt with their inner submissive and masochist yet. they're just as afraid that they're not 'real men' for liking to submit, so they lash out at people who remind them of that, the anti-ntr brigade.
they use the ntr fetish porn because it feels good, but haven't yet understood why they like it. this too is very common with homophobes. they secretly consume gay porn and even have gay sex, then hate themselves for it, and in public attack gays to cover it all with anger.
anger is the sign of a scared coward.
