Strange, because 90% of what comes out of LISPers is proselytizing (or touting their own horns, which serves the same purpose).

That's mostly because we get annoyed when we see old things being marketed as "new" and "hip" :) That's not proselytizing, that's snobbery.

Well, macros, closures and GC haven't been "new" or "limited to LISP" for like 40 years.

So, if LISP had them since 60 years and others got it 20+ years later than that, hardly matters by now.

It does matter when Lisp is not given due credit.
