How do you tell a good one from a bad one? They look exactly the same. This is how; you just have to wait for the bad one to get caught, by law enforcement/military authorities, blowing shit up, and killing innocent people. The only way to end it is by the general Muslim population themselves to stop being indifferent/bias to & in favor of the extremists terrorist Muslims, and turn them in or take them out themselves. One would think, by association, both being Muslim, the extremist causing the good, normal, kind, & gracious Muslims such grief, they would want to clear the mess up themselves and get back some respect in the world. So, how do you tell a good one from a bad one when the good one tolerates the bad one?
