This is contrary to the findings of anthropology. I recommend Mothers and Others by Dr. Sarah Hrdy (yes, Hrdy, not Hardy) for an accessible primer on the topic. The TL;DR is that it takes almost 20 years and 2 million calories to get a human from conception to ready to have children of their own. Meanwhile, siblings are spaced out every 4 years or so in hunter-gatherer societies, meaning that the work needed to maintain a family is more than a pair of humans can manage on their own, and death rates by hunting accident are high enough that there's a decent probability that half of the pair isn't even going to be around the entire time. The only effective strategy to ensure a given child gets the support that they need to survive to adulthood is if nobody in the band knows who sired which kid, so that all the men will chip in a little for each one and if one man gets chomped by a lion or gored while hunting a buffalo, his offspring will still have enough caretakers to ensure they make it to adulthood and pass on his genes to the next generation.
There's marked differences in proposals WRT all kinds of sex-specific policies between the two major parties in the US, from abortion access to pay equity. With the thought leaders the divide is even more stark, with some conservative commentators (including one woman I can think of off the top of my head who's been popular since the 90s) openly lamenting that women even have the vote. And, yes, there's been a constant theme for at least the quarter century or so I've been paying attention of one side brushing off male infidelity (sometimes by even turning the blame onto the wife for having a career instead of dedicating her life to pleasing him) while excoriating promiscuous women even when they stay single and therefore aren't cheating when they play the field.
Every single game thread on this site that I've ever looked through has an argument about NTR. It's so pervasive that the other day I noticed somebody had even coined the term "ntrguments". That there's one particular tag that so consistently gets pushed when it doesn't apply indicates there's more going on than mere stupidity, and the fact that it's the tag for games that portray female promiscuity in the most negative light is too convenient for certain ideologies to be a coincidence.
I say: bring on the all-harem, all-horde orgy scene! Bring on Sheeriku grinning triumphantly while splattered with five different (humanoid) species' cum!
People who say porn shouldn't even exist while themselves secretly consuming it say: OMG! Women can only be monogamous and if they're not it is violence against me as a porn player! Tag this with a tag that doesn't apply so I can avoid the traumatic idea that women can possibly be interested in more than one man at a time!
As I read your points are as follows:
Among primates and early humans extrapar relations are a necessity for reproductive success
I think for a specific point in evolutionary history this might have been the case for humans or at least our ancestors. But I can find studies showing males are less likely to provide paternal care to offspring they think aren't their own. I can find studies showing that male extramarital sex is much more prevalent throughout most cultures in the world. Given that my original argument was biology, going to far into cultural adaptation happening after our last evolution is probably not a way i want to go with this.
I don't think it is entirely inconceivable that our cultural evolutions stem from our biology though. Having social norms and early laws spring from our desire to survive seems perfectly logical to me. I will give you that early primate reproductive success might favor a sort of flock mentality in regards to sexual relations.
I think this drastically changes in early human society though. Ancient Greece, Rome, Egypt, Mesopotamia, and Israel all developed and had laws favoring monogamy.
Conservative politicians having a different take on pay equity or abortion is to dismiss female promiscuity while being accepting of male promiscuity
You have to remember that in the mindset of a conservative, the other side of pay equity arguments are not that women should earn less than men (I assume this topic is relevant because you equal money with the ability to sleep around, which I agree with). The other side of arguments regarding pay equity is that it already exists. Any data showcasing women earning less money than men has to also present what careers we are talking about and individual factors like how big a part of their life each person's career is.
There is nothing misogynistic about women favoring lower paid jobs, in fact the few women that do work in male dominated fields and have equal education might even get paid more than their male counterparts.
Now remember, we are not arguing the glass ceiling, i am showing you that in the conservative mindset, any additional laws regarding pay equity would either be unnecessary or outright discriminatory.
It is the same with abortion. The conservative mindset is either that abortions are ok but should not be founded by tax or that they are bad and we should fight for preserving life. None of these lines of thought directly prohibits a women's ability to sleep around. Not in a world where contraceptives exist. I see there is actually an argument here that women having less money equals less ability to pay for contraceptives, but on this side of the aisle, the amount of money you have equals the amount of effort you put into earning money, and lets face it, contraceptives are not that expensive.
For me to present the otherside of the argument about a theme you have noticed about celebrating male infidelity and shaming female, i would need specifics because I am not familiar with any such cases.
The ntr tag on f95zone is negative, and is being pushed to artificially add negatively to games portraying female promiscuity.
My own take on the fetish is close to yours. I basically just want all kinds of sexual relations. Watching people fuck comes first. It doesn't matter if there is a story about cheating or incest involved. In fact I think it is paradoxical to be heavily against other people having sex when that is basically what pornography is.
This anti-ntr crowd is very verbal and the mere inclusion of it in a game will completely ruin their entire experience. I have no idea how this works. I can easily play
Discipline -The Record of a Crusade- and just fast forward through the scat (something I personally think is a turn off) while this anti-ntr crowd can't do the same for an ntr scene.
If we assume you are right and there is a group of people wanting to use the NTR tag to negatively promote games featuring sexual kinks they don't favor I would much rather pin this on stupidity or immaturity than political beliefs. I at least do not see the correlation.
