Let me explain my thinking. In society, there is a problem called sexism. In those societies fortunate enough to have achieved a high degree of formal legal equality between the genders (the UK, the USA, Canada, and many other countries besides), there remains the problem of sexism; a problem which takes many forms, such as women being underpaid, under-represented in certain jobs, suffering from sexual abuse and rape etc.
The purpose of feminism is to remove this sexism. The victory condition for feminism is a society without sexism. Fine. But what is sexism? Broadly speaking, it is a set of beliefs and attitudes that are widely held about how women should behave; and these beliefs and attitudes are held by *everyone*, both men and women. These beliefs and attitudes are the *cause* of the various inequalities that exist between the genders (again, this obviously only applies to those countries that *don’t* still have inequalities enforced by law).
In order to combat this sexism, we must endeavour to change people’s beliefs and attitudes. Now, because many people will deny that they *do* hold sexist views, this process of changing beliefs will require that we first persuade people that a problem exists in the first place. A great deal of sexism is ‘subconscious’ sexism that manifests itself in things that don’t happen as much as things that do happen (e.g. women’s lower pay may be attributable to men simply not thinking to offer women promotions. While it is difficult to *prove* that a particular woman has lost out, the macro-level evidence is clear.). Once we have successfully persuaded people that a problem exists we can persuade them to change their beliefs and hence change their behaviour.
But here’s the problem: the vast preponderance of sexist beliefs are held by men, and the vast preponderance of sexist behaviour is performed by men. This means that at some point the feminist movement will have to persuade men that a) many men hold sexist beliefs, and b) that these sexist beliefs cause those men to behave in a sexist fashion.
So yes. The feminist movement needs men. It needs to include men. In fact, the victory condition of feminism would be one in which *all* men were converted to feminism, and in which all men were good feminists (i.e. non-sexist).
I think the problem here is that the OP conception of ‘the feminist movement’ seems to be some sort of army or corporation, with hierarchies and bosses at the top – bosses who OP says can only be women – and which does… something, somehow, to combat sexism. Like as if sexism was a foreign army of people that you could defeat on a battlefield. But sexism isn’t like that.
I sincerely believe that we are more likely to succeed if we are polite, and if we make our arguments rigorously and calmly, because we are right. I don’t think feminism will succeed if we insist that feminism is transformed into some kind of ‘no boys’ social club for women.
