They probably did not tell you this at Sunday School. 1 Samuel 18:27 : If you check your old testament/torah you will find forced circumcision has been a feature of religion/culture for millennia… Gods are obsessed with detached foreskins it seems. Check out the brideprice David pays for Michal, daughter of Saul (100 Philistine Foreskins asked – David goes 2 for 1 and delivers 200 Philistine Foreskins to Saul as tokens of dead Philistines) “David took his men with him and went out and killed two hundred Philistines and brought back their foreskins. They counted out the full number to the king so that David might become the king’s son-in-law. Then Saul gave him his daughter Michal in marriage.” Of course Saul could have asked for Philistine heads – too tricky to carry, or hands – possibility of cheating with women’s hands – so foreskins! In this case the story suggests post mortem genital mutilation.
2014: The Tunisia Daily is reporting that the Islamic State (ISIS) forcefully circumcised Assyrian men in Mosul, without anesthesia. The report does not specify the number of men that were affected but does state that it was an organized mass circumcision. ISIS has ordered the circumcision of all Christian children and adults who remain in Mosul.
