Why the hate on Islam, my brothers?

People have a tendency to over-generalize, you know. Those extremists who kidnap, torture, kill people in the name of Islam have stained the fame of ur religion; moreover, some muslims are slightly conservative, they don't regard themselves to be guests when they move to other countries where residents don't practice this religion..This is understandable if you look on this phenomenon from the angle of disparities of economic development; I mean some people ask others to respect them but they never respected others. In ur opinion, the radical Islam isn't Islam, but many people are judgmental and prejudiced by nature, they don't care if it is real Islam or not.
