As an aside, I strongly recommend Iannucci's The Death of Stalin [1], which is in US theaters right now. The material would be horrific in a serious film, but treating it as a black comedy makes it endurable. I enjoyed it much more than I expected, and the cast is first rate.
The fact that some people once wished the word "communist" to mean something else doesn't matter much. Post-1945 it has had a clear meaning: the empire of Stalin, and its vassals, imitators, and admirers.
"as envisioned" just means some people once told a fairy tale about how nice things would be. The Heaven's Gate cult also "envisioned" riding to paradise on Comet Hale-Bopp.
...is extremely ambiguous, context dependent, variable. Especially for words ending in '-ism'.

Then don't use words from the extreme end of the range of vapor words. Instead, talk about something concrete.
