In the wake of school shootings there is a call to restrict gun access. But does this really get to the heart of the problem? Most mass shootings are perpetrated by young males without a father in their lives. Author Warren Farrell said “Without dads as role models, boys’ testosterone is not well channeled. The boy experiences a sense of purposelessness, a lack of boundary enforcement, rudderlessness, and often withdraws into video games and video porn. At worst, when boys’ testosterone is not well-channeled by an involved dad, boys become among the world’s most destructive forces.” If you're a father, may I challenge you to do everything within your power to make your son a priority and be there for him? You may be the best measure to safeguard all of us against future acts of mass violence.
