We educate our children to be wary of strangers. We must heed our own advise, no exceptions. You must be prepared to defend against everyone you meet, especially those whom you let enter your safe zone on any pretext. To do otherwise is to live in denial, with unfounded hope, and surounded by the ignorant flock. Aspiring to spiritual, mental, and emotional strength is commendable, but the warrior mentality and the physical security it endows must be the foundation.
