Well if you are judging a religion by the behaviour if its people then that is a mistake, ofcourse these people shouldn't give the bad impression about their religion, yet a person with open mind should be able to see beyond that, you would not judge a family because of a bad kid, or a country because of a bad citizen, or a religion because of a bad follower, look at christians today, everyone walking with the cross, yet totally contradict what they are supposed to do, i mean porn stars wearing cross and goin on saying they are christians, strippers, murderers in prisons, ...etc. then what are you gonna say, those aren't true christians, so can muslims say that those kids aren't true muslims or aren't following the pure islam.
now about violence, this is a problem created by the media, try and watch how when any muslim guy does anything the media always relate it to his religion, or mention he is a muslim, or say he converted to islam then did that, even if its a crime that has nothing to do with religion at all yet they mention it just to give such impression.
go travel to any muslim country, live in that community for a while, violence has no place, you don't see people walking with guns, you don't see stand offs and shootings all day as in la or ny, you go on saying muslims are violents just because you didnt like the behaviour of some individuals, well iam sure as bad as their behaviour was, it wouldn't be as scary as what you see everyday from your own fellas ,
and finally talking of violence, look how muslim communities been under attack in various parts of the world all over the past 30 years, and that violence is by countries that have christian majorities, , so who is the violent one? and if we don't want to go down that argument , well why is it that when some people in palestine or iraq show some passion to their land and fight for it and resist occupation you guys go on relating it to religion, while you know very well they are doing it for the land not for the religion,
the whole thing is whenever anything is done by a muslim its related to his religion, when they fight for land you say islamic terrorism, when they dress conservative you say radicals and fundemantlists, when they dress free you say contradicting themselves, when they do any kind of human misconduct that all people in all nations do, you say oh because islam told them to do so
maybe if everyone stopped being too brainwashed to the point that whenever anything is done and the world muslim is out in the air they relate it right away and blame it on their religion, muslims might do mistakes, but only because they are human not because their religion told them to, and if everyone was treated with same mentality, then christians will have a hard time fighting such propeganda!!!
