A way to look at this is how many people from northern Europe are terrorists say Swedes, Fins, Norwegians, Poles, even the dreaded Russians, British, Germans etc. verses those from countries that have been at each others throats for centuries. Now wouldn't it appear that it's sort of ingrained to bring that with you. Statistics seem to show that so wouldn't you think it wise to err on the side of caution. I can see why you would criticize a shift key as that seems about as far as you can see. Read the content and try to understand rather than just look for faults.
