Why? Both are a disenfranchised voice complaining with violence. One might be more valid than the other, but that doesn't mean one is inherently better.
No, they are not. Not at all and that you think that is exactly my point. One is the voice of a group that has been in power throughout the history of this country and the other is a group that has been oppressed by the former group.
One group is using violence to maintain their power, while the other is using anything they can to make their lives better.
