I am sorry, but Peggy Seeger is on record as stating that what she and MacColl were trying to do in the critics group was to train teachers. When discussing the break-up of that group she said that maybe the people were ready to got out, ready to be teachers themselves, but she and Ewan had not appreciated that. This was in a recently broadcast BBC TV interview. I have to choose whether to credit Seeger or you. I am afraid that on balance I feel Seeger is more likely to be correct regarding the intentions she and Ewan had.

Regarding the rest of your post, I don't have the time or the inclination to respond. You are welcome to the last word, and people will make of it what they will. It isn't really an issue.
