it's just the way this world is - ignorant. people categorize everyone into groups and then judge accordingly. you can't take one minor aspect of a group and then try to apply it to all. it simply doesn't work.
there are some people in the world who are very violent. and they come in all shapes, sizes, and religions. if we want to analyze the extremist muslim agenda, we have to ask why are they so violent? no one just fights for no reason.
if you had a chance to speak to these people you will find they all have different reasons for the violence. i promise you that 99 out of 100 times, they were peaceful muslims, as most are peaceful, had something horrible happen to them. the major story we hear is that they had their families blown up by someone. now if another muslim blew up their family, their aggression would be directed towards other muslims. but it's not directed towards other muslims. it's directed towards white christians and jews. there's a reason for this.
why would a peaceful muslim become aggressive and attack white christians and jews? obvious. they are the ones affecting their lives in a negative way. muslims aren't flying planes into any chinese or japanese landmarks. they aren't blowing up south american countries! they are specifically attacking european, US, and israeli nations.
now think about it. if you were just a plain ol' violent person, your aggression would be directed toward everyone, not just a specific group.
basically, these people are fighting back against aggression that was placed on them in the first place. where did this aggression come from toward muslim people? GREED! COLONIALISM! IMPERIALISM. think about it. israel stole palestinian land. why wouldn't they be upset and want to attack israel. if someone stole half your home, what would you do? europeans and americans have been interferring in the middle east (as well as africa) for centuries now. and the list goes on....
keep in the mind the backlash from south american countries as well.
you have to ask yourself, while the media is concentrating on muslim violence, why in the world does everyone (including some allies) despise and totally hate the USA and European nations? Why do muslim people denounce israel?
you think it's because they hate freedom or is it because they love freedom? how can you experience freedom when some foreign entity just snatched half your home and is interfering with your neighbors? it can not work this way.
this violence and violent attitudes are going to continue until this nation and others STOPS INTERFERING IN OTHER SOVEREIGN NATIONS. for example, those weapons of mass destruction that they "know" saddam hussein had in iraq were given to him by our own president reagan (maybe was an earlier president).
anyway i answered the question in the first paragraph. the rest of this was for the obvious ignorance that litters the answers to your question!
