Whose fault is it, anyways?

Every time I read some report about girls who left their families to join isis, I feel sorry about them and their families but I also wonder about why they did what they did. For young European girls to leave their aspirations, their homes, their dreams, their freedom, is something that is disturbing as well as it opens the floodgates of questioning minds. Why would a girl do that and who is to be blamed? The parents that failed to integrate, the school that failed to notice the change, the society that failed to accept, the social media that is ever effective in spreading mischief, or the authorities that failed to take action?
One thing is there that the parents failed to give the real picture of the world and left the us versus them feeling in the minds of their children. Further, a false picture of Islam is also painted, a picture that shows that the western world is evil. Yes, it is true that post 911, islamophobia has increased and the terrorist organization take advantage of it to lure gullible youth that has failed to mingle in their society towards itself. While men go to join the jihadist, the girls go to marry these mass murderers. For a girl to give up her dreams to marry a criminal, is something very sad.
Religion is something to be practiced within closed doors. Outside a person should try to be a good human being. Morality and humanity is above all the religions of the world. Universal brotherhood is a fact that needs to be preached everywhere. People tend to keep themselves secluded from different cultures and also societies feel reluctant in accepting new people. This feeling of us and them needs to change. Evil doers wait for these opportunities to brain wash young people by saying that only they can provide them with good life. It is all a lie. A rapist, a murderer, a terrorist will never provide a good life or a meaning to life. A misguided person cannot guide anyone.
