I suppose my reaction to this is, if you remove all the grievances and the mental illness from feminism, what do you have left? What part of feminism forms a body of consistent thought which people can actually believe or act on to make society better?

When I was younger I tried reading some works, mostly newspaper articles, by feminists like Germaine Greer. What I felt was that they seemed to shift around their positions to maximise the aspect of grievance, complaining that things just aren't fair for women, even though things aren't actually that fair for men, we can't just pull out our "patriarchy card" and receive rich rewards as a result. I couldn't identify any actually-useful outcome of feminism either for men or for women.
