Have never heard a reasonable counterpoint to this fact. Guns were more prevalent in the lives of Americans long before these mass shootings became so common. I don’t know the answer but something in our societal fabric has changed specifically with young men. I personally think secularization has been a major contributor. Young men are losing their souls and the results are frightening.B) We didn't have these mass killings even when full military weapons were legal. Blaming guns for something that is obviously a cultural problem isn't helpful.
