Sheila Rowbotham said this quote

There is a difference between having your own movement and cutting yourself off politically from all other movements. This last form of feminist isolationism is attractive in its simplicity. It appears to offer an option which implies that you concentrate on your own struggle and wait for some absolute future when men and women have progressed towards equality. It is of course a profoundly liberal utopian notion. ‘Progress’ is seen as some kind of single linear advance towards a goal. There is no sense of a movement living and working in history, learning though a dialectical interaction of its own efforts in objective circumstances. It forgets that the consciousness of particular groups amongst the oppressed is only partial. While this consciousness must be realized and expressed in their own movement, if the attempt is not continually to extend and connect this partial consciousness to the experience of other oppressed groups, it cannot politicize itself in a revolutionary sense. It becomes locked within its own particularism.
