As in muslim invasions for 1,300 years, there are no civilians. Mein Koran commands the faithful to kill all Jews: men, women, and children, the "spawn of pigs and monkeys".
No one should thank that islam was the first cult group/tribe to live genocide as its creed.
Is it nature or nurture?
Well technically you are not true, woman are good sex slaves (so kill ugly ones) and kidy is good on retail market also as property.
