People of certain cultures are very trapped in their societal structures, expectations and taboos.
And I feel quite strongly it's not for us white Westerners to wade in there and tell other peoples were they go 'wrong' (in a patronising white missionary kind of way). We do all sorts of things that are incomprehensible to other cultures: breast augmentation/reduction, facelifts, 'tummy tucks' - yes, some of these have medical justification, but the majority don't. And one could argue that these procedures are done due to social pressures (to look a certain way) too.
HOWEVER - people how have plastic surgery for whatever reason do so voluntarily, they are not forced and held down, sometimes by their loved ones. They hope to achieve a better quality of life by undergoing painful operations (that sometimes go wrong causing longterm problems).
(As an aside, and please nobody pick a fight about this, one could argue that the need to look a certain way leading to plastic surgery is a similar pressure to what Somalian girls/women feel when they continue the tradition of FGM?)
Having said all that, we have duty of care to ALL children in this country. And that includes ensuring that they are not taken 'on holiday' to their homecountry only to come back mutilated.
How on earth to achieve this, I have no idea.
Tbh, the relationship of many British people to their bodies is such that I can just imagine many caucasian, native British families not agreeing to have their children undergo an intimate examination (even if it was just an inspection) as a matter of routine.
And I really don't see how you can just single out Somalia/Ethiopian/other African girls for this.
I am so glad this is more of a spoken about problem at present.
