Yes.This is exactly what has happened. DIR was put out to the world in the late 90's...It was never modified from then on, and the world has changed. GUE DID change, with the times..Their language and context reflects this.
In an earlier post I said that the historical information that led to this comment was very helpful. It was helpful because it showed how very specific phrases that are still being repeated and used in the DIR world had very different specific meanings in their original context, meanings that are lost without the context. To say it was illuminating to me is an understatement, and I am someone who has learned a few things about DIR over the years.
I would think that an essay describing those specifics, an essay that could be repeated on the current DIR-related websites as often as the 20-year essays are, would go a long way to helping people understand.
As I have said before, people who dismiss this as a matter of ancient history forget that these words are still being read and applied today. That means they might as well have been written yesterday.
