Are saying that cuckholdry is for intelligent people? That's very soy of you. Any race that participates in cuckholdry is low IQ. You're basically admitting that your race is inferior and in need of better genes.
It's due to whites buying into dumb abstractions such as "equality", "bodily autonomy" or "deconstructing patriarchal and racist impulses" and not seeing the world as it is that leads to cuckoldry.
Other races don't have these kind of problems. They instinctively know that might makes right, namely, that we live in a world of limited resources, so it only makes sense to take as much as you can by whatever means it takes, because everyone will inevitably do the same.
Same goes in the case of cuckoldry: why would one let another individual enjoy the body of the women he himself put time, money and effort to obtain the access to?
