We may be converging, but I'm not sure.
I think it is still incredibly useful for feminism to look at these things as 'women's issues'.
Sure, I don't have children. But, as a group, childless women still face the discrimination of employers assuming they'll go off and have children and take time off. They still face the knock-on effects of there being fewer women who can act as mentors to them from higher up in the career path, because many of those women were pushed out when they had children. Basically, they still face the assumption that they belong to the child-producing, child-caring sex and they still suffer the fallout of actually belonging to that group.
Obviously, they don't have anything like the same experiences as women with children, but if we don't refer to this as a 'women's issue', it becomes less obvious why women are doing less well than men at careers.
And people really do struggle with this one - you get lots of people who simply don't know that childless women might be passed over for jobs because the assumption is that women will go off and have babies, and that lack of knowledge comes as a shock to them when they experience it. If we talk more about 'women's issues' and less about 'the issues that affect the people already affected by them' (which is the alternative), we get a better sense of what is likely to happen to us before it does happen.
