I've seen multiple times where the mere mention of possible NTR content greatly pissed some people off. I don't fully understand the hatred but to each their own. Some people don't understand "softcore" porn either and think it's a pointless waste.
TL;DR - 1st Paragraph. :]
Put simply (and these reasons do not apply to every respective individual in question nor is it all-encompassing), it's been explained to me, repeatedly, that a significant portion of that "hate" (strong word there, boss, btw) stems from the fact that those users likes to
self-insert into the games or other media and they don't like the idea that their LIs or other pursuable characters can be stolen or have other relationships other than from them. Even for those users who do not self-insert, they want to be or guide the "hero" of the story and be the only one who can get the characters they're interested in. This mindset applies regardless of the gender of the real individual.
And that's perfectly fine. People like what they like and what they don't. We can all respect that. We all have our own preferences. It's also alright to criticize some aspect of a game or other media and have healthy discussions about it. That's fair too. But what is
not okay is folks disrespecting other people's preferences, kink-shaming or belittling them, or things along those lines because of what they prefer instead. That's when the line gets crossed, and such posts should be nipped in the bud quickly.
For example, I like the games
Seeds of Chaos and
Our Red String and they cast a wide net in their content that people can explore. However, they also have a lot of things I never want to see in them either and that's true for other people as well reflecting their own desires. Yet, despite that the conversations in those discussion threads are mostly
civil and respects the each poster. People get along just fine, like mature adults. There's not a lot of hate and discontent that some folks like to spread just because they can or in their misguided attempts to persuade others that their kinks are "wrong". Instead, people have a healthy discourse about the various topics those games bring up such as the things they like or dislike, the mechanics of the game, or some other feature or issue. In actuality, I believe more threads are like that than not -- being civil and respectful. And yes, occasionally the haters can be very vocal, but I feel that real
hate and browbeating others is in the minority. This was what was explained to me and my take on it. Be safe, y'all, and get your lewd on, lol! ;]
