I know this is a strange forum to be asking this question, but my question is how and why does religion even matter to people or terrorists or fanatics. I mean, why can't people just let people be? Believe in what you want, worship whoever you want, why do people have to impose their beliefs on others? A simple analogy would be: If I believe blue is my favourite colour, why are there people telling me that pink is better? Why can't I just think for myself and believe or think whatever I want to believe in without being blasted into bits, or seeing people dying just because their favourite colour is blue or pink.
