From about 1975, as radical feminism began to fizzle out as a force in feminism, a new framework (I refuse to say p***digm) called cultural feminism got going, and absorbed many (former) radical feminists. Many of us carried the name "radical feminist" with us, and some of us now-cultural-feminists use that name to this day. Maybe denial, maybe not. If so many of us radical feminists (though, to be truthful here, I was a very young and very new radical feminist in 1975) joined the cultural feminism school, one might imagine that radical and cultural feminism would be similar beasts.
This is not, in fact, the case - the difference between the two is quite marked. Radical feminism's goal was to transform society, whilst cultural feminism retired (in the military sense - and don't forget, we're talking war here), and strove instead to build an enclave of women's culture. As radical (and other) feminists became disillusioned about the very possibility of social change in any reasonable time-frame, many of them turned their attention to building alternatives, such that if women could not live safely in the unborn society radical feminist strove for, instead they could build this enclave of women's culture. If they couldn't change the patriarchal society, they could at least avoid it as much as possible.
And that is what the shift from radical feminism to cultural feminism was all about. This change in goals and modus operandi enabled cultural feminism to make changes in society that we see around us today, in a way that it is very unlikely that radical feminism could have achieved (not that it was trying to). Today we have shelters for women, rape crisis centres, governmental anti-trafficking organisations, etc.
These changes were accompanied by reasons explaining and attempting to justify the abandoning of working for radical social reform. Ideas such as the idea that women are "inherently more kind and gentle" were among the foundations of cultural feminism, and remain a major part of it. A similar concept held by some cultural feminists (including me, though of course I'm a radical feminist really) is that while various sex differences observed in our society may not be biologically determined, they are still so thoroughly ingrained as to be intractable.
And that's cultural feminism. Not that I'm a cultural feminist. No Ma'am.
