oh my god , why these people can't speak about some science rather than each one's fairy stories . some days before i watched some terrorist videos made me vomit they are really enjoying killing people like , the worst thing i ever seen in my life , it was so horrible and i never got the idea behind this cruel act , slaying down the necks of human beings in half and enjoying , unfortunately facebook block that video , it would be a eye opener for so many people who still thinking about violence rather than making peace .i lost my faith in God after watching that video .
