Why are people so unwilling to recognize the Ft. Hood macre as an act of terrorism?

Don't start labeling Obama over Ft. Hood. Damn it, the Military needs to get serious on removing people that could have that wild mental dream of killing many people based on the wars or their ideology. Yes, I understand Nidal Malik Hasan is a Muslim, and he did acted that way, but damn it, isn't it time to mourn the people who died at Ft. Hood instead of being hateful over Obama?
