I can't, because I wasn't the one who downvoted it. (I can see why one might think so, since the comment was in response to my comment).

Your comment thoroughly explores possible routes for improvement in ability in a novice programmer who has knowledge of Python; probably to a far more detailed level than the author of the original "go read a book on Lisp" comment. I saw nothing it it that requires a downvote, but no particular benefit in continuing the original debate (debating a comment more thoroughly than the person who originally made it, in the absence of the person who originally made it, is only of particular benefit if at least one person firmly agrees with the original statement; while I think I can see where it came from, it's a matter of indifference to me).
