It's going to be a little big, so I'll leave it as a spoiler.
i can't speak for others, but for myself.
I don't care if there is NTR in a game or not. I also don't judge any player because he loves or hates NTR. Every person has a different taste and/or kink, and that's absolutely fine.
All i want, is that people start to accept that there is not just global NTR. There is netorare, netorase and netori.
These are complete different things.
While netorare (NTR) = some other person has sex with MY LOVEINTEREST and does that without me knowing and/or with intention to take my love interest away from me. (2 complete stranger people fucking is NOT netorare therefore)
netorase = can be cuckolding and/or sharing. It is a WANTED situation where the player either WILLINGLY accepts to look at others while they have sex (cuckolding), or even participates (sharing).
Finally there is netori = player takes someone elses loveinterest away (actually every player having sex with a married neighbor woman got netori content).
EDIT:
So what about a situation where i see 2 complete stranger having sex then?
Easy answer: it's called "situation where stranger having sex" - there is no term for that - why even should there be one?
/edit
But again - whatever a player choices - i am fine with it - i just pled to use the terms correctly and not start to call every situation where you see another man having sex as NTR - not more. This is the definition of these 3 terms netorare, netorase and netori, and i can't accept people just change the meaning of NTR just because they refuse to adapt to the terms. To be honest, i doubt most of the NTR-crying player don't even know that there is a difference. They just parrot whatever they THINK what's NTR and don't even care about the real meaning at all.
EDIT2:
Finally - what about my neighbor married woman, being my love interest, but having sex with her husband? is THAT NTR?
NO - it's a "married neighbor which is my loveinterest having sex with her husband".
It's no NTR as the husband doesnt try to take my love interest away, as he doesn't even know that i and his wife having an affair.
In fact, it's ME trying to take HIS wife away from him -> therefore it's netori for me (NTR for him, yes - as soon as he get's knowledge and see us having sex)
