I came across this post and was bothered by it.
Mainly what bugs me is the read I get off it that feminism and capitalism are in necessary opposition. From what I see of capitalism it has no particular call to reinforce sexism or other oppressions and indeed might function more effectively by not doing so. The problem with capitalism perpetuating societal oppressions is I think a matter of historical contingency, and if a hypothetical world without sexism were to invent capitalism I doubt the people of that world would also invent sexism to accompany it.
None of this, of course, vanishes the practical issue of women who claim feminism and vote or act politically against the interests of women generally.
There were also some remarks in a later comment which peeve me in a personal way.
But its time we get back to our roots and say “we are against all oppression, all hierarchy and in support of autonomy, make your politics follow us!”.
Honestly, we have to ask what feminism is about. Are feminists against all systems of oppression, or just the ones that personally afflict them? Are they only against patriarchy or against other/all forms of hierarchy?
I see plenty of feminists complain about people, often men, saying feminism ought to be renamed something more inclusive like humanism - and rightly so, as typically these proposals exist as part of a pattern of behaviour which has the effect of impeding feminism by refocusing attention on men and the concerns of men (which is strictly unnecessary, since men are also beneficiaries of reducing and eliminating sexism and these attempts are mainly manifestations of the incompleteness of that liberation).
Anyway, my annoyance is the confluence of those complaints with the pervasive attitude I perceive from feminists that feminism is a movement against all oppressions. It is pretty well impossible to untangle one form of oppression from another, but to claim membership of a anti-specific-oppression movement entails opposition to all forms of oppression seems a bit much. I would rather see feminists claim to be for example anti-racism on the basis of being anti-racism, rather than in some way suggesting feminism forms the heart of anti-oppression overall.
Plus, if pressed to identify my values one way I'm likely to answer is humanist, for reasons broader than merely anti-oppression politics. I don't appreciate seeing feminists object to the term humanist yet claim feminism means anti-all-oppressions when it would indeed be a more fitting term for that attitude.
 Except I think capitalism would have a difficult time not driving some sort of classism.
