I'm wondering if this concept is a cultural-based one. Especially since I was doing some reading of historical primary sources and came across something interesting. In summary, I think the applications of mate-guarding vary between cultures and this can lead to an overall different dynamic.

Western societies, as demonstrated through the present and past, are more relaxed when it comes to mate-guarding. This leads to an overall normalisation of the AF/BB theory. For example, wife-selling was a practice in England before Divorce was possible. As quoted from a blog from the Leeds Trinity University: "Generally, wife-sales occured with the consent of both the husband and wife, with a buyer (new husband) in mind, who was often the wife's lover if there had been an affair" Historically, how old this practice is varies. According to Menefee, he believed that it was an Anglo-Saxon practice which began as early as the eleventh and twelfth century.

This sounds very... relaxed to me. And considering that the focus of this sub is very Anglo, I think this attitude is demonstrated in red pill theory too. Especially with the mantra "it's not yours, it's just your turn"

And contrasts in these attitudes are demonstrated through a medieval source by Ibn Munqidh (1095-1188), who was a Muslim warrior and courtier, writing from 1175.

He wrote:

"The Franks are void of all zeal and jealousy. One of them may be walking along with his wife. He meets another man who takes the wife by the hand and steps aside to converse with her while the husband is standing on one side waiting for his wife to conclude the conversation. If she lingers too long for him, he leaves her alone with the conversant and goes away.

Here is an illustration which I myself witnessed:

When I used to visit Nablus, I always took lodging with a man named Mu'izz, whose home was a lodging house for the Muslims. The house had windows which opened to the road, and there stood opposite to it on the other side of the road a house belonging to a Frank who sold wine for the merchants. He would take some wine in a bottle and go around announcing it by shouting, "So and so, the merchant, has just opened a cask full of this wine. He who wants to buy some of it will find it in such and such a place." The Frank's pay for the announcement made would be the wine in that bottle. One day this Frank went home and found a man with his wife in the same bed. He asked him, "What could have made you enter into my wife's room?" The man replied, "I was tired, so I went in to rest." "But how," asked he, "didst thou get into my bed?" The other replied, "I found a bed that was spread, so I slept in it." "But," said be, "my wife was sleeping together with you!" The other replied, "Well, the bed is hers. How could I therefore have prevented her from using her own bed?"

"By the truth of my religion," said the husband, "if thou shouldst do it again, thou and I would have a quarrel." Such was for the Frank the entire expression of his disapproval and the limit of his jealousy. . . ."

I think the eastern attitude towards this is very different, and that these two attitudes are prevalent today. The issue that the west has nowadays, as mentioned repeatedly within complaints, is that of social media. Such shame and loss is easily presented (and the situations are accelerated) through this medium. And the current attitude of red pillers and MGTOW is one that resembles the wishes of implementing a gender dynamic similar to that of the easterns... but without making the moves to redact the freedoms of individuals. Id argue that the east is a lot more community based and always has been, and so preventing freedom of individuals and having stricter gender roles is more culturally natural
