Circumstition on young girls in Africa raises concern!

Hundreds of Muslims and Jews marched side by side along the streets of Berlin in protest of  circumcision to be carried out in a sterile environment, with “as little pain as possible” (assumed to mean with local anaesthesia) and only with both parents’ consent. For both faiths, that was an attack on religious freedom.
The merits and costs of circumcision in women  has also been a big issue in Africa and is under scrutiny as never before, by human-rights activists and health professionals. Why is such  ritual on young girls circumcision not banned? who should be blamed ? culture, authorities or selfishness?
