This is a pretty racist story that completely ignores very recent events of mass shootings by non whites.  San Bernadino?  Seattle?  Orlando nightclub shooting?  
And the line "All across America white men, some young, some of middle-age, are turning into wolves."  Gee, some hyperbole there?  All across America?  Oh, so the author acts as if this is happening monthly, maybe even weekly, and that no state or city is immune.  This author is a complete loon.
