I saw her comment and just pushed it to one side and thought there must be more to this.
But on the other hand she has no grounds to complain about lack of support as the Guardian promoted her (not of course because she was young and photogenic) as a brave new voice, when they knew (or certainly should know) that FORWARD was and still is a well established African women's organisation based in the UK that has been campaigning of the issue, and the related health problems of fistula for decades.
And far from the left not support the issue, the founder of the group was supported by leftist groups to get started. en.wikipedia.org/wiki/Efua_Dorkenoo
It's not for me to comment as to whether women in need of support would prefer to talk / work with women from their own culture, ie I dont know if Daughters of Eve have a different slant than Forward, but I do know that many in the voluntary sector were taken aback by the Guardian sort of presenting Nimco Ali as a pioneer.
Maybe there was some issues of competing for the same grants.
But either way, trying to say Boris Johnson is a feminist is just implausible. Given his entrenched white male uppor class British privilege it is much more likely that he was thrilled to have an issue that would let him say how shocking it is that women from BME communities are so oppressed.
