Comments on LISP are not noise in comp.lang.lisp.
Answering an old post is not trolling.

What's the noise-to-LISP ratio of /your/ comment
quoted above?

Perhaps unlike you I remember the person who systematically did exactly
this thing in exactly this way, with exactly this aim of systematically
denigrating CL (notice their 'Instead of CL, let's use a Lisp' comment?)
in, I think, late 2000s, I think perhaps because someone in the CL
community had been nasty to them. That time I think their chosen language
was Ruby? That person helped destroy cll, as was very clearly their aim.
It looks as if they have woken from their narcotic slumber and are now busy
trying to make sure cll stays dead. Clearly they were then and are now not
well in their minds, but also clearly they were, and are, a troll.
