It's also the moments when sisters need to get together for this thing I'm interested in.....we'll do your thing later and later never comes
And what is 'your thing', exactly?
We all have multiple levels of experience and condition - regardless of sex, race, nationality, ethnicity, religion......
Feminism is about women uniting on the basis of sex, and the conditions and things they have in common on account of their sex.
It is easy to find common cause with other women, wherever they may be, whatever their social background. the shared conditions of womanhood are the same pretty much the world over.
If we all refused to have empathy with, or work with women from different cultures or backgrounds we wouldn't get very far. I think some women end up 'choosing' to see their social class or their ethnic background as their most defining feature or prominent identity - and in doing that they find division with other women - and cannot see common cause.
