Compare an contrast two mass murder events in the US.
The Fort Hood shooting. Nidal Malik Hasan, shouted Allahu Akbar before killing and injuring dozens of soldiers on a military base. The left downplayed the part Islam played in it and preferred to call it workplace violence.
Their biggest fear was a backlash against other Muslims in this country.
Charleston, SC. The left is quick to call it a terrorist attack, and to blame all white people for the actions of one crazy racist asshole. It's almost like the left wants to instigate revenge attacks against white people.
Fortunately, the caring and loving people are having none of what the race-baiting left is offering, and are calling for calm and forgiveness, not more violence.
