Nothing annoys me more than weak people who tip-toe around awful problems in order not to offend the followers of that certain wonderful religion. Being hesitant when it comes to such a vile issue should be an immediate sacking.
FGM is an abhorrent practice that needs to be completely stamped out, and those to subject women to it should be prosecuted.
Also, which religion are you referring to? I mean you're clearly intelligent and knowledgeable to know it's not just one particular religion involved in this, with the practice covering a number religions and similar cultures.
