I'm talking about the present day, all races of humans are supporting each other and working towards women's equality. Feminists today shouldn't disregard any women for their race... they're trying to help all women, not some.
Historically, rights for any group experiencing injustice hasn't been a concern for people not suffering from the source of discrimination. So there are denominations of different movements fighting for the same thing.
You can see this trend in the past 300 years of revolutions. I noticed this first in a history class where I learned about a woman in France who was inspired to pursue more freedoms for women during the French revolution. Apparently, this wasn't a concern for the men who were opposing a monarchy to improve their quality of life at the time. Eventually, she was killed, and I want to say it was because this was seen as rebellious. It was along the lines of rebellion, but it has been a while since I took this class.
So the trend continues. The men fighting in the american revolution didn't fight for the rights of women. The women in the women's movement didn't fight for the rights of black women. The men in the civil rights movement didn't fight for more rights for black women creating a second women's movement for black women by the ones who were experiencing the injustice.
I think this phenomenon occurs because people lack empathy and they are selfish most of the time. People like to give where they will either find praise or individual relief of something that affects them personally.
So the women's movement has not existed as one movement because of this and still remains separated at times. However, it was not created by the Rockefeller's at any point in time any more than unions were created by Rockefeller's. Sometimes, people are treated badly and they have to stand up for themselves and that is what the women's movement is about.
Fortunately, in the present day after so many of these individual movements have been collected to create a whole, it is more about supporting and working towards the cause of women's rights together rather than individually.
However, I think we also reach another extreme where our present generations haven't struggled in a way that truly allows them to understand the previous movements, and so their interpretations of these movements are sometimes superficial and unnecessary.
