Exactly. And as you point out, it's a social justice issue and human rights issue as much as anything else.
Bill, you seem to imply ME is a new name for the illness ('other recent name changes...'). It's not. It's an older name for the illness. Chronic fatigue syndrome is the newer name, and the less accurate one. It may be more accurate for you, and you are free to use it, but for many of us, it doesn't encapsulate the experience we have.
You're also missing a huge point: ME and CFS are only equal if the criteria used to define them are exactly the same. They're not. As others have pointed out, they're overlapping criteria either on a spectrum or in some kind of Venn diagram. ME criteria define a more specific, usually more disabling condition than CFS criteria. They're not interchangeable terms, even if they're used that way, since a person using CFS is referring to the NICE, Fukuda, Oxford, Reeves or Holmes definitions, while a person using ME is referring to the Ramsay, London or ICC criteria. Similarly, SEID is not identical either.
But really, I think this discussion needs a new thread (as was suggested earlier). It's become a too-long digression from the main topic.
