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.
Hope in the power to change yourself. Talk to men. Actively support women's struggles. Acknowledge difficulties, deal with the ones you can, identify and be honest with the ones you can't. Anti-sexism involves us in positive and creative action.
