This paper explores the negative impact of sexism on both women and me
n and considers what active part men can play in challenging and under
mining sexism. The costs of living and working in a patriarchal societ
y are outlined, and related to the differing experiences of women and
men. It is argued that, although women clearly bear the brunt of sexis
m, gender stereotyping is not without significant costs for men. This
leads us into an exploration of possible anti-sexist strategies that m
en can promote and implement as part of the development of anti-discri
minatory and anti-oppressive practice. The aim is not for men to 'colo
nize' or take over the struggle to achieve emancipation from oppressiv
e gender norms. Rather, it is for men to play a part in the collective
struggle to remove the inhumanity of patriarchal social relations. Th
e paper is grounded within a professional value base premissed on a co
mmitment to combating discrimination and oppression, and within a theo
ry base informed by existentialist philosophy (Thompson, 1992a).
