While I definitely don't agree with FGM being performed, you probably should look more into the topic than you have.  The Qur'an never directly states female genital mutilation as being part of purity.  The video you've included in your article even says that religion isn't the reason.  FGM was condemned by leading Islamic scholars acting under the Grand Mufti of Egypt in 2006 as being against Islamic values, and many of the countries in which it is practiced are trying to illegalize it.  More women surveyed by Orji and Babalola thought having FGM was important because it prevented the death of newborn males than women who did it for religious reasoning.  Yet you focus your article mostly against Islam rather than the cultural ignorance.
