"These are good good goals however you can not operationalize them without taking first step of inclusion, sharing the media, the stage, the dance."
You are a step behind.
The first step was having Seeger and the Smothers GET a stage to share their opinions - they were the ones who were excluded from the media, stage and dance.
There were not JUST singing to those who agreed with their view. It just isn't true that that they were preaching to the choir. Even if they were, that choir deserves a forum too.
You keep failing to recognize that one basic FACT.
