Well, to be perfectly fair...there are women (for example, living in America) who have the circumsion done on the younger females at medical establishments if they can. A lot of establishments/docs won't perform it though in the US.
The rest of what you say it true however; mostly done in Africa. Frequently performed by a member of the community of the area; even worse, if they can't find anything sharp, they use broken glass or other contaminated utensils.
**Edit: I claimed it was a Muslim practice, when really it is practiced by many religions within Africa.
**Edit AGAIN: FRICK! I said it was exclusively done in Africa...it's MOSTLY done there, but also in other areas.
