Terf - what would I do? I don't know, is the answer. It is easy for me to sit here comfortably in my middle class existence and fantasize about being the brave, awkward individual who bucked the social norms around me and made a stand against the familial and social pressures surrounding me and refused to iron my daughter's breasts. I'd like to imagine I'd be a hero. Whether I would be, I don't know.
The practice is at its most prevalent in Cameroon, and interestingly, there's conflicting reports on where it takes place. A lot of reports presume that it's confined to poor, rural areas with low education levels, but I've also read one report suggesting it's more prevalent in cities, driven partly by higher levels of sexual violence in crowded cities, and partly by desire to ensure your daughters stay in education. Cameroon has one of the highest rates of female literacy in Africa, but also has high rates of child marriage (something like a quarter of girls are married before they're 18) and teen pregnancy (about 20% IIRC give birth while still teenagers).
It is a horrific practice, with long-term after effects (abscesses and destruction of functional breast tissue).
Back on the topic of the thread though - I simply don't get how schools and youth organisations can condone breast binding when it is so obviously damaging. I presume it's because the likes of Mermaids send round endless literature telling teachers that kids will commit suicide if they're not allowed to bind their breasts - which for me rather suggests we need much, much better mental health care for adolescents, not turning a blind eye while they mutilate themselves.
