I think there is some truth to that. When you are young, you have really only had time to give serious consideration to one angle. As you get older, you are given time to start to ponder other angles, and will naturally want to discuss those other perspectives to see how they fit into the big picture. The problem, however, is that those who only have one angle of perspective start to equate what they can think of and with what they believe. When someone suggests a different perspective (questionable ones included), it is assumed that is their belief, but in real world there is a clear separation between ideas and beliefs. Often the points are presented simply to understand the nature better. After all, you don't really understand something unless you can argue several different points of view.
