Until the advent of materialism and 19th c. dogma, Western Civilisation was superior to anything Islam had developed. Islam has not aided in the development of the modern world; in fact civilisation has only been created in spite of Islam. Proof of this resides in the 'modern' world and the unending political-economic and spiritual poverty of Muslim states and regions. Squatting on richer civilisations is not 'progress'. Islam is pagan, totalitarian, and irrational.
Munafiqun within Islam is associated with apostasy and being a 'hypocrite'. It reinferences a Moslem who does not follow the totality of Muhammadan-Sharia fascism, or Bronze-age ideals and Muhammadan contract law, named by Western Dhimmis as a legal code.
"Hypocrite." In early Islamic history it refers to a fairly specific group of "Muslims" in Mad?na who nominally accepted the authority of the Prophet of Islam, whilst working in various covert and overt ways to hinder his mission." [Joseph Lumbard, “Islam Fundamentalism and the Betrayal of Tradition”]
The allusion to hypocrites and the need to kill them abounds in the Koran and the Hadith. They are as dangerous and satanic as the Jews or Christians. The Muhammadan cult cannot survive unless the Munafiqun are purged.
3:116 Surely, those who reject Faith (disbelieve in Muhammad SAW as being Allah's Prophet and in all that which he has brought from Allah), neither their properties, nor their offspring will avail them aught against Allah. They are the dwellers of the Fire, therein they will abide. (Tafsir AtTabari, Vol. 4, Page 58).
2:27 Those who break Allah's Covenant after ratifying it, and sever what Allah has ordered to be joined (as regards Allah's Religion of Islamic Monotheism, and to practise its legal laws on the earth and also as regards keeping good relations with kith and kin), and do mischief on earth, it is they who are the losers.
4:138 Give to the hypocrites the tidings that there is for them a painful torment.
66:9 O Prophet (Muhammad SAW)! Strive hard against the disbelievers and the hypocrites, and be severe against them, their abode will be Hell, and worst indeed is that destination.
Apostasy is punishable by death. Munafiqun is a form of apostasy. You pretend to follow Mein Muhammad, but in your private life you don't and are 'striving' against the cult, 'doing mischief'. Sura 5:33 is very clear that those who 'do mischief' can be killed, executed, humiliated and crucified.
This is why Moslem fascists like the Taliban have no difficulty in shooting Munafiqun Moslem children in the head; or why Moslems the world-over will kill anyone they believe is disobeying the Koran, including their own family members.
