I found the arguments lurched from "Scheme is a Lisp because _____" to "It would be nice if Scheme were abitrarily designated not a Lisp because _____" and possibly "It would be nice if Scheme did not exist because _____." This page needs some editing to put the arguments onto a common basis for comparison. There are three things being discussed, two of which are relevant to the title and one which is not. First, what test or tests define whether language X is a Lisp. Second, does Scheme pass these tests. Third, is it advantageous to "Lisp" the community or concept or whatever for Scheme to be considered a Lisp. The third question has nothing to do with whether Scheme is a Lisp as defined by the first two questions.
