The Bible pretty much is the best guide for non-aggression. Why? Because all the forms of accidental and intentional aggression are dealt with properly, according to the non-aggression principle, in the Bible.
New testament is fairly non-aggressive. But the Old Testament! Oh my 
OT should be flagged as "not for under 18" because it contains some explicit violence. Its principle being "an eye for an eye, a tooth for tooth" would turn the whole world blind and toothless.
But you must already know this. Check out Buddhism or M. Luther King if you want to know what non-violence is.
Sorry for the off topic, but I'm sensitive to exaggeration.
