the koran also says 'do not commit aggression for God does not love aggressors'. for a very short answer to your question, when the koran talks about killing infidels it is meant in the context of self defense, NOT terrorism. but you (like other extremist) want to interpret certain passages as you see fit. the stench of irony should be strong in your nostrils by now...
what about the passover? how about moses and the red sea? the plagues of egypt? all in the name of christianity. does that mean we should go out and kill all people suppresing gods people? NO!!!!
i'm not going to get into religion bashing because it's counter-productive and off topic. the point is even though the koran says what it says, the bible also has teachings which can be interpreted in the same manner and taken to extremes. accept it and move on.
