I don't know how old you are, perhaps the term feminism holds a different meaning now than it does to someone who was around in the 60's and 70's. The whole point of feminism is to secure equal rights and standing for women under the law, and in society, we've come a long way baby, but we have yet to fully secure equal rights in things like equal pay for equal work, and equal opportunities for promotions based on things like performance, as opposed to choosing a qualified male candidate over an equally or better qualified female candidate when both have children at home, but it's assumed that she would run right home if the kids were sick or something, and he would not. We also have yet to achieve equal representation of our numbers in government, which is still predominantly male, and even in the last presidential race, while we have finally broken a color barrier, we have yet to break the glass ceiling there. Feminism is exactly what it sounds like, the point and purpose is to support the cause of female equality and standing to male, if she is Domestic Goddess, a carpenter, or a CEO of a fortune 500 company (yeah, right.). Certainly a feminist can be an egalitarian, but if feminist organizations have gone on to a more general cause of egalitarian causes all across the board, then they have steered away from their purpose. There are other organizations in place to promote egalitarianism, and other groups in place to right more specific wrongs for a more focused approach for specific groups of people. Those who work toward the cause of equality of women are feminists. Should feminism be named something else to make it more "acceptable"? If feminism needs to be named something else in order to be more "acceptable", that only goes to show that they are still a very long way from accomplishing their mission and purpose. Feminism has never been fully "acceptable". Far from it. And we like it that way, it means somebody's uncomfortable, and if they're uncomfortable, we "done hit a nerve". Words have power to focus, to crystallize.
"Egalitarianism" would not focus the cause for women as "feminism" does. Wouldn't it be a nice way to dull kitty's claws a bit though?
To be honest, the only time I have ever heard the term Feminazi was from Rush Limbaugh, and I've always had the impression he considers all feminists to be feminazis, no matter how liberal or hard line they are.
All groups have their fringe elements, so what else is new?
Should mainstream Democrats stop calling themselves Democrats if some lean too far to the left? Should mainstream Republicans stop calling themselves Republicans if some lean too far to the right?
