I do know some of the history. I was just asking those questions as a challenge. Regarding the question of the other dialect, the parent used the term as a way of distancing Scheme from what I assume is the one true Lisp: Common Lisp. But the point the passage they had an issue with noted two dialects. The other, of course, being that one true Lisp. The way I see it, the things that make Lisp "Lisp" are not exclusive to either one. One might say that the intersecting characteristics aren't interesting, but these characteristics are what Lisp is truly about. SML and Caml are both ML. Haskell 98 and Glasgow Haskell are both Haskell. Dyalog APL and APL2 are both APL. And so on.
