If that is true why dont muslim leaders condemn such act of terror. Most of the times they are defending their acts. Thats why it leads other people to believe that it is associated with religion.
Check out som eof Anjum Choudhary's video posts on youtube, you will realise what I am trying to say. He is a muslim leader from UK. If anyone sees him or people like him in action, they are bound to associate terrorists to Islam. No matter what you say.
