There is a longstanding theme within Western culture of men who dream of rescuing the damsel in distress, perhaps with the reward of a relationship for their efforts. It all seems noble and idealistic, but it has come in for criticism within the men's movement, to the point that the term "white knighting" is now a derogatory one. As it should be.
The thing you notice is that white knighting always seems to exist as part of a pair. When men engage in white knighting, women engage in the feminine imperative. And both, especially when existing together, are a sickly version of what the genuine relationship should look like.
The feminine imperative is the idea that men should sacrifice for, and be servants to, women. Or, to put it another way, that men exist to serve a woman's goals and objects (and that a woman therefore has no reason to be grateful for what a man, or men, might do for her). Here is an example of the Christian version of the feminine imperative:
She believes that even as the "head" of a family men are only there to sacrifice and serve, whilst the woman leads.
There is some basis for white knighting and the feminine imperative in our biological drives. Men do, after all, have an instinct to protect women and it also makes sense that young women, as the bearers of children, might be thought especially critical to the future existence of a tribe.
Even so, the white knight/feminine imperative axis is dysfunctional. Women who succeed in turning men into a servant class are making them romantically and sexually unattractive. Women are generally more sexually attracted to dominant men they find difficult to tame or control. Which is why the white knight strategy also fails spectacularly for men - it is not likely to lead a man to the end part of the fantasy, where he wins the woman.
This is what makes white knighting so lame. It is a poor strategy for an individual man, or for the men of a community, to follow in attempting to win the favours of women. It ends up not with women casting admiring glances at their rescuers, but in women feeling ungrateful to men they cannot respect or have a genuine attraction to.
This does not mean that men should not follow through with their protector instincts. But this instinct needs have a higher aim, namely the protection of the larger setting within which relationships can successfully take place. The male protector instinct should be applied to upholding the virtue of women within the culture; to defending the culture of family life; to preserving the position of married men as having status and power and therefore attractiveness; and to creating a protected space within which the feminine qualities of women might be cultivated.
It's not reasonable to expect that a man can do this alone, as an individual. It will only happen if and when numbers of men act together to reset the culture.
