I going to keep this short. After the news of the Sikh temple shoot out in the US, the floawed reasoning seems to be: A white guy mistook some Sikhs for some Moslems. Therefore, it is OK to target Moslems but not to confuse them with Sikhs. The above photo shows the Sikhs among us (part of the UNIFIL in the south), just don't mistake them with Moslems (whom you are allowed to target).
