There's "lot to unpack here" as the kids say when cheating on the priestess is "vanilla" but her getting railed by orcs is NTR. Not trying to start anything, just find it pretty funny.
Lol, wut? Try and spot the common theme in the following:
>When the dog shits on the floor it's "no big deal," but when I do it everyone loses their minds
>When the cops put strangers in a cage they're "keeping us safe," but when I do it it's "kidnapping"
>When the government takes your money at gunpoint it's "necessary for a functioning society," but when I do it it's "armed robbery"
Need a hint? They're false equivalencies.
Also, even fewer people understand what vanilla is than what NTR isn't. Flatly-written, soulless, bog-standard harems aren't vanilla, they're harem--which is a separate category for a reason. Vanilla is when
love is written into it. When you feel warm and gooey inside and you either start to feel like the world isn't such a shitty place or, at the very least, that even if you never expect to have a relationship as wholesome and fulfilling as the characters have that you can forgive yourself for wanting it. It's possible to do that in a harem or poly, hypothetically, but it's rare enough to see this between two characters that I wouldn't hold my breath.
Dipshits who hate the "emasculation" of being cheated on but love the "empowerment" of getting to cheat because he's such an attractive fuckboi? Yeah what idiots who are extremely insecure wouldn't have this insane cognitive dissonance.
See above. Losing a fight sucks, winning a fight can range from sucking less to being the best feeling ever. In both cases you're fighting and we haven't established any sort of context, but when you can only have one winner and one loser the goal is to not be the loser.
That's all it is. Really. People want more of what feels good and less-to-none of what feels bad. The people who like getting cucked want more of that, the people who hate it want none of it. I'm not going to get into the logic or economics of this because it's an h-game and doesn't fucking matter, but behavioral ethics is not a "one-size fits all" subject in the same way that algebra isn't always solved by adding everything together and quality of life
doesn't infinitely increase as you earn and spend more money.
