People focus on this because it was an act of domestic terrorism, like Ft Hood, or Oklahoma City, the attack on the Holocaust Museum, Eric Rudolf. In fact this type of assault on historically black churches has a long precedent in this country.
That's how terrorism works, it focuses attention. Nothing wrong in acknowledging that and condemning it.
Just heard the church's former Pastor interviewed as he traveled back. He knew 7 of 9 victims, including the murdered Pastor. He said that it was a moment to come together as a family and that 'revenge is not ours'.
Tunnel vision stops people from seeing the root causes of a tragedy and by not seeing them they can't be dealt with so they will be repeated. Society has developed into this madness, welcome to the world of the progressives.
