A brief description of what is Christianity and what is Islam. Why knowing this is important ? All over the world, we notice, Muslims are being radicalized no matter they live in Muslim countries or developed western countries. Why Muslims living in the western countries will be radicalized and will try to destroy the society where they live. Why such hatred? Why Muslims always blame others for their own chaos and conflict ? What they actually learn from Islamic Imams, Alems or Islamic Scholars and Preachers? What make them so radicalized that they desperately try to attack his fellow people among whom they live in. Is there any problem inside Islam, or in Christianity ? Muslims are not happy in Muslim countries, they are not happy in non Muslim countries, but why ? What do they actually want and why western people and politicians still are very reluctant to knowledge this problem ? Why do not they understand that Muslims are actually availing the opportunity of Political Correctness and freedom of speech, and rights, just to infiltrate into the western society to destroy it from within. Are all those politicians just traitors or too ignorant ? What is the fact ?
