I don't care if news outlets won't call it terrorism so long as they will call it a hate crime, because there's an element of terrorism inherent to a hate crime - there's always a political reason for someone to single out a particular group of people and they're always intended to strike fear into other people in that group. If the media was portraying Roof as a one-off lone wolf then I would think differently but all bar Fox are calling it racism, and there's plenty of that in society that would've inspired him, so they are looking into the root cause of this shooting
“The larger the group, the more toxic, the more of your beauty as an individual you have to surrender for the sake of group thought. And when you suspend your individual beauty you also give up a lot of your humanity. You will do things in the name of a group that you would never do on your own. Injuring, hurting, killing, drinking are all part of it, because you've lost your identity, because you now owe your allegiance to this thing that's bigger than you are and that controls you.” - George Carlin
