Why is feminism so small in number
I think you'll find that most women are actually 'feminists' - in the sense that they are women, and come at life from a female view-point. Even if some reject the label.
Been watching some documentaries over the last few days of confinement ( first all-woman round the world yacht crew, and the 1970 Miss World Pageant...) and even though many/most of the women, at the time of the particular events, would not have described them selves as such - later they most definitely did, on reflection.
The descriptor 'Feminist' still seems to have an unsavoury reputation, and many women still want to "be nice", and to placate - as their first instinct. They don't want to be seen as a "angry man hater".......
Equality of opportunity, and equality value is not the exact same thing as equality of outcome.....In fact, once equal civil rights have been achieved, then it is clear that differences and individualities come more into focus.
Women are not exactly the same as men. And not all individuals are the same, regardless of sex.
