There is now little room for doubt that Dylann Roof killed nine people at Mother Emanuel AME Episcopal Church on Wednesday night because they were black.
It was an act of racism. It was an act of evil.
Evil will always be among us and racism is one of its more virulent strains. Unfortunately, this means racism will always be among us. The best we can do is to inoculate ourselves against racism from an early age and if an outbreak does occur to stop the disease from spreading. More often than not this country has succeeded in this regard over the past half century.
