I think the media is very influential on public opinion, many wrong opinions about islam, individual crime or terrorist group does not reflect on islam, I believe all religion teach kindness to others 
I agree, we are forced to think a lot, because in every religion there are fanatics who cause anxieties and killers...I don't think that this relates to religion, because religion teaches us to love everyone around, and if a person sees in these teachings the message of murder, then this is a matter in man, not in teaching
