Congratulations! You apparently are one of the few who can hear a point and absorb it. However, most have to hear something over and over to grasp it. Take for instance the numerous lies the media and zero tell over and over. Truth is if something is repeated over and over - then people believe it. Hence we have libs who believe lies all the time even when they are slapped in the face with facts.
The Druids practiced an oral tradition. Committing an idea to memory was usually accomplished by repeating the information 3 times. Notice the radio advertising business repeats the key message 3 times in an ad. It’s a time tested method.
