You know, as a strong independent woman, I'm going to have to respectfully disagree.
If you look at Maslow's hierarchy of needs, I have the first two levels covered. My basic physiological needs are met, as are my safety needs. I'm a first-world woman who lives in a safe area of the country. I have an education and work in a stable field, so the basics are all sorted.
However, that leaves three whole other levels of need where the involvement of men is very useful to me--namely, love and belonging, esteem, and self-actualization.
I need men in my life to give me a sense of love and belonging. Certainly, I can get that to a degree from women, but men are half the planet. I want to have a sense of love and belonging from the breadth of humanity.
Also, there are significant ways that men can address esteem issues that women simply cannot. It's not that the input of women doesn't matter regarding esteem. It's just that we need to develop confidence and competency in many areas of our lives. There are some areas that are best addressed by men.
When it comes to self-actualization, I've found men to be particularly helpful to me. There are ways that men have seen and cultivated my potential that women have not. It's not that women are inadequate. We just see the world with different eyes. There's a way that men push and say, "Is that all you've got?" that makes you dig a little deeper and do more than you anticipated you could.
These are real NEEDS in my life...not wants. In the absence of these needs being met, I suffer. It pains me if I don't have a sense of love and belonging from men. There are areas where my confidence is slipshod or very thin without the input of men. And there are things I'd probably consider, but not push myself to try were it not for the encouragement of men. So far as I'm concerned, men have a great deal to contribute in meeting the needs of women--it just may not be the low-level needs that they anticipate.
