I said that about monotheistic religions (Christianity, Judaism, Islam) we practically believe in the same G-d!
Untrue. Xtianity views Divinity differently while Islam worships a monotheistic version of the Babylonian idol of the Moon Allaht and his 2 daughters Al-Uzza and Al-Menaht.
But there are many extremists, fanatics and fake believers on different ways,that is the problem!
When it comes to Islam "extremism" is the very faith, Al-Qaeda didn't hijack anything but basically did what Muhammad did 1,400 years ago - wage Jihad for the eliminiation of Al-Kuffar and have the Islamic sword of Allah rule the world.
And who are the "extremist fanatic fake believing" Jews you are talking about?
If somebody is a Muslim its mean that he is evil?!
A Muslim by definition is a person who accepts the 6 Pillars of Islam (Sitaht Arkan al-Islam): Shahada (evidence of faith and acceptance of Muhammad as the last Prophet of Allah who is the only G-d and his massage as viewed in the Qur'an), Prayer (Salach), Ra'ma'da'an Fasting (Saum), Charity for Jihad (Za'akat), Pilgrimage (Khajj) and Jihad.
These are the basic principles of the Islamic faith, and a Muslim who does not accept them is not a Muslim.
And he who accepts these principles of faith in one of the worst Jew murderers in history, from whom Hitler had learned, and his Nazi war-mongering "massage", and a global war for Him (Jihad) that is nothing but a war of murder, rape and enslavement of all non-Muslims all over the world, is a Nazi.
