Christians in Egypt practice FGM ?

I find that very hard to believe.  
According to an article at BBC,  it's not just Egyptian Muslims who practice FGM but also Christians.  If this is not true, Westerners whose origins are from Egyptian Christian lineage should take the BBC Newsnight's Sue Lloyd-Roberts to task for such claims that make people like Richard Dawkins drool with delight on finding additional munitions  to carry in his  "The Atheist's Tool Kit."

BBC reports FGM rife in Egypt despite ban. http://t.co/wDDUqJJl5W Practised by Christians, not just Muslims. Religion poisons everything.

In 2008 Egypt outlawed the practice of female genital mutilation,    but as Newsnight's Sue Lloyd-Roberts reports in an article which contains graphic detail and which some readers may find disturbing, the ban has had little effect and the practice is still rife....

.....The practice is not restricted to Muslims, as has often been claimed, but also carried out by Christians, who make up 10% of Egypt's population.
The practice predates the arrival of either religion in Egypt - there is evidence that it was practised back in Pharaonic times.
It is a deeply entrenched tradition, which is why it is proving so hard to eradicate......
