Allah sez in the koran that killing is a requirement for all pious muslims dreaming of entering that whorehouse in the sky called paradise. You cannot argue with allah.
Koran 4:95 Not equal are those of the believers who sit (at home), except those who are disabled (by injury or are blind or lame, etc.), and those who strive hard and fight in the Cause of Allâh with their wealth and their lives. Allâh has preferred in grades those who strive hard and fight with their wealth and their lives above those who sit (at home). Unto each, Allâh has promised good (Paradise), but Allâh has preferred those who strive hard and fight, above those who sit (at home) by a huge reward
And you assume the words 'strive' and 'fight' mean killing people?
If all traditional, religious Muslims believe they are supposed to kill anyone who is not a Muslim, why, when I have lived in 3 different Muslim countries, did no one try to kill me? Why were they friendly, kind, helpful, and sociable to a non-believer? Why are there Christian churches in Muslim countries? The Bible says to do a lot of things people no longer do. Contemporary Christians do not do everything the Bible says to do. If they did, we would all be living an even more fundamental life than modern day Christian fundamentalists. There are things in the Koran and in the Bible that are no longer relevant to modern people. Most Muslims are as modern as anyone else. Muslims are more than 22% of the overall world population. There are billions of them. Only a tiny fraction of a fraction of them are terrorists or support terrorists.
Just some 'laws' laid in the Bible that modern Christians do not follow:
Deuteronomy 17:2-7 Kill anyone with a different religion.
Deuteronomy 13:5
Anyone who dreams or prophesizes anything that is against God, or anyone who tries to turn you from God, is to be put to death.
I Corinthians 11:6:
So if a woman does not cover her head, she should cut off her hair. If it is a disgrace for a woman to cut off her hair or shave her head, let her cover her own head
I Corinthians 14:34-35:
Let your women keep silence in the churches: for it is not permitted unto them to speak; but they are commanded to be under obedience, as also saith the law. And if they will learn any thing, let them ask their husbands at home: for it is a shame for women to speak in the church.
Leviticus 20:9 Any person who curseth his mother or father, must be killed.
Leviticus 21:9 If a priest's daughter is a whore, she is to be burnt at the stake.
Leviticus 24:14-16
Anyone who curses or blasphemes God, should be stoned to death by the community
Leviticus 21:17-18
People who have flat noses, or is blind or lame, cannot go to an altar of God
Deuteronomy 13:6-10
If anyone, even your own family suggests worshipping another God, kill them
As well, modern Muslims, like modern Christians do not follow such extreme guidelines.
