Until that survival is threatened, if so.. the biological wire for response to threats is activated. Women being built differently than men, do not have access to a physical violence that would give good chances of the threat being neutralized, and as such need to use different methods. One of which includes a threat identification and anticipation.Women aren’t biologically wired for competitive behaviour between themselves and other women, they are biologically wired for cooperation and nurturing others, for mutual survival.
Part of that early anticipation is to address potential threats preemptively and proactively. Some of that can be manifested in suggesting potential sources of threat of stability (other women) to cut their hair short as a way to diminish the potential threat to the stability that ensures mutual survival. Yes, some women do this consciously, but those are probably pathological and do not represent the majority of women, but probably most do it unconsciously.
It truly isn't controversial in my view, and I think that most anyone can understand what is being described, both men and women. If anyone's ever felt jealousy, then you can understand what the article describes, or the mechanism that would initiate the behavior the article describes.
The article does not deny anything you've said in this thread so far, but somehow it has become something you wish to stand against. That is, you've made the same points the article's made, only you're making them after saying that the article is wrong for the making the same points.
