(Note: What follows are generalisations based-upon biological differences - there are exceptions; but exceptions are exceptional, and should be regarded as such. Social arrangements may reshape or distort the generalisations; but such arrangements need to be purposive, powerful and permanent - since they are trying to re-mould what happens spontaneously. If you dispute what it said below; bear in mind that this is almost-certainly not because of evidence, but because you have different assumptions by-which you are interpreting the evidence.)
Women react very badly to being told they can't (or even shouldn't) do any particular thing; even when they don't actually want to do it.
So (evil) feminism seems to work by telling women that they are being excluded from this or that - by a conspiracy of men.
This is termed the 'patriarchy' - and is supposedly an omnipresent-yet-occult peer-group conspiracy of a kind that does not spontaneously exist among men (who mostly compete with each other - or cooperate in hierarchies); but is normal among women (who spontaneously conspire for social goals, and punish other women by social exclusion).
So women can get very angry about being excluded from horrendous situations, like frontline combat situations in wars; despite that it is only very rare and unusual women who actually want to take part in such activities (and indeed, the majority of men would certainly prefer Not to be in such situations!).
This is why women (in general) feel, or can easily be made to feel, that being excluded from things they would actually hate to do is equivalent to being shunned.
Another example is professional mathematics, physics and engineering. Only a small minority of men, but a much smaller minority of women, actually want to do these things as a first choice in life (even when they are good at them). But even women who would loathe to do this work can get very angry if they are brought to believe they are being kept-out of it... which, of course, they aren't; quite the opposite for the past several decades.
Women project female motivations onto men; just as men project male motivations onto women; and this is quite natural and spontaneous because it is how we understand other people: we use our own emotions to model those of others. And this is why it is so easy to fool so many women into assuming that men operate in the ways that women do.
And it goes further than this; because men and women perceive Life in different ways - I mean the whole business of the human condition is seen differently: Women see life more socially, men see life more functionally.
Therefore, by a kind-of paradox... From a task-functional perspective, the fact that only few and exceptional women want to be in a situation (or are able to do it, due to sex differentials in ability) is sometimes exactly why women actually ought to be 'kept-out'! (...as a generalisation, with exceptional exceptions...)
As the adverse (and increasingly-adverse) experience of recent generations suggests; the mixed sex situation has intrinsically so many dys-functional aspects, that it is generally to be avoided when functionality is the priority. There are, of course, exceptions - usually time-limited - such as when functionality is so strong or urgent a priority that it psychologically overwhelms the problems of mixed-sex groups. For example in acute emergencies, or during war.
Task-functionality is a mainly masculine ideal - and in a pure form is pretty rare even among men, and easily corrupted by short-termism and selfishness. Nonetheless, most men see an 'ideal' world in terms of functions, and how best to accomplish them. The difference is not in the ideal, but in whether it can be lived-up-to.
(Perhaps this is why talking-about sports is so popular among men, since sports are about 'how to' accomplish tasks: how to win. Men often enjoy spending hours talking about how their team might play better, might win more... task-functionality in action.)
But even if at lower levels men are mainly motivated by selfish-short-termism; task-functionality must dominate the leadership group; if performing a function is genuinely intended.
Men who are genuinely interested in functionality, and who have gathered in self-selected groups of other such men, nearly always experience the presence of women as disruptive to functionality.
This is not-at-all surprising; since adult mixed-sex functional groups are an extreme evolutionary novelty - just a handful of generations even in The West. We are not evolutionarily-equipped to task-function in mixed sex groups - we not being assisted, but rather thwarted, by our 'instincts'.
From the male perspective of task-functionality, 'women' (in general, and as a group especially) tend to hijack task-functionality into 'social dynamics'; since men see the world in functional terms, and women in social terms.
A single exceptional women, in exceptional circumstances, may share task-functional goals with self-selected men (history provides several examples). But because task functionality is so extremely rare among women (especially in some particular areas such as maths, physics, engineering and the like); any group of women will not be composed of such rare exceptional types; and therefore any group of women will almost-certainly tend to (try to) hijack task-functionality into social dynamics; because that is simply how groups of women experience reality.
Thus women reshape the externally-orientated functional male environment into a social female environment of networks - with its focus on dynamics... bonding rituals, a kind of peer-group-norm 'egalitarianism'; and psychodramas of favouritism, exclusion, shunning.
And this is precisely the nature of modern bureaucracy, and therefore of all modern social systems.
Modern organisations have no real external task-function (what they have is a mere badge, a fake rationale, an excuse) - and have mostly given-up on task-functionality. All large organisations are bureaucracies, and all bureaucracies have become mostly, qualitatively the same: their main activity is inwardly-directed 'office politics'.
The female ideal of work-life as social dynamics has displaced the male ideal of task-functionality: the workplace has been remodelled around group dynamics, instead of accomplishing some role.
Of course - none of these 'public space', organisational activities really satisfy women - because what is really most-wanted by most women (spontaneously, naturally, deeply) is a family.
Being a unit of human resources in a bureaucracy can hardly be expected to substitute for being a mother to children. Yet this is indeed what is expected - and the superiority of the workplace to the family is massively-pervasive propaganda, explicit and implicit, in the mass media and officialdom directed at women.
Women increasingly build failed lives on the false motivation of resentment-at-exclusion.
Thus we wreck the effectiveness of the entire public realm in The West, in trying and failing to provide a idealised female-friendly environment; in a misguided and destructive (and ultimately evil-motivated) attempt to substitute work for family for the majority of women - when this is only valid for rare and exceptional women.
And the motivation that drives this is resentment, based on false projection of female-onto-male psychology.
