I don't think Jesus' comment about turning the other cheek meant that he wants his church's members to just meekly allow themselves to be murdered en masse by a lunatic who apparently had "issues" with Christians or Christian churches. A slap on the cheek won't take a young mother away from her children for the rest of their lives, but an armed lunatic's bullets would.
God speaking through Moses instructed Jewish rulers and judges to punish evildoers by taking life for life, eye for eye, tooth for tooth. IIRC the Old Testament book of Exodus contains a passage of scripture that authorizes using deadly force against burglars if they break into your home after dark to steal valuables or to do you harm, and that scripture was written by the same God except in human flesh who talked about turning the other cheek 14 centuries later.
There are many who think they do with some regularity.
