Quite the opposite I'd say... in my experience, Lispers tend to say "Lisp" when they are being inclusive of the whole family of languages & its philosophies. This convention began way back in pre-Common Lisp days, when there was literally no common standard: much as we say "Unix" to refer to the family of related-but-different OS's that once proliferated. Generally I've seen capitalized LISP used only to refer to the original language, from McCarthy's lab (e.g., versions 1 and 1.5). By the time Interlisp landed in the late 60's, the all-caps convention has already begun to slip. That's not to disagree with your own experiences: I just suspect they are "regional", so to speak, and not reflective of the larger Lisp community.
