To specify that the peace movement wasn't progress.
Most people that I knew who glorified the 60's were far more involved in the peace movement than civil rights. They are the ones that I have the strongest impressions of, and hence the ones that I ranted about. But my impressiond second and third hand of the civil rights movement are much better.
Hence my (rather significant) qualification up front, exactly to exclude the civil rights movement.
Cheers,
Ben
