This is aptly named 'feminist-fucking'. The best use by men of feminist theory is to develop a critique of men's behaviour and thinking and awareness of the possibilities of change, not the development of a critique of feminism. We should explore what implications feminism has for men's position in the world. In academia, we can examine the practice of existing, often patriarchal, academic disciplines. For whatever thing or field you are interested in or working within, whether it's health education, architecture, ecology or economics, there is a relevant body of feminist thinking that you should check out.
Men can certainly explore feminism in ways that are constructive and practical.
Affirm that you can change. Be willing to listen and learn. Accept criticism and learn to use it for personal change. We are the problem. Silence is complicity.
