Dennis Prager has a talent. He can put a concept into words that anyone can understand. Here's a case in point. In A Young College Grad Calls My Show he describes a conversation he had with the caller.
The caller had trouble reconciling the concept of good and evil with the moralistic ambiguity he was exposed to in college. Here's Prager:
What Jeff said is what I was taught at college. It is heartbreaking to hear how effective left-wing college indoctrination continues to be, with its morally obfuscating concepts such as “too complex.”
The morally obvious fact is that the United States is overwhelmingly a force for good both in the world and within its borders, and Syria is overwhelmingly a force for evil both in the world and within its borders. Yet colleges have taught for at least two generations that such judgments are illegitimate.
If you want to judge whether Sweden or Denmark is better, that’s complex. Or whether Iran or Syria is more evil. That, too, is complex. But between Denmark and Syria, there is no moral complexity.
There's evil in the world. A person doesn't have to be religious to understand that there are people in the world who will hurt and kill to get what they want. Putting it in terms of good and evil shouldn't be that difficult of a concept, and Prager does it expertly. He concludes on a funny note by saying there's hope for the kid since he listens to Prager's show. (Heh heh.)
