I'm afraid I just declined a very amusing comment simply because it was typed in with so many bits of carelessness. Never forget that I am really just an usher.
I've also declined one or two recently, purely on account of my own whimsy. In one case it was because of the condescending manner in which, with no reference to facts I thought I was working with, it advised me that Common Sense knew better. In another case, the writer seemed to want to make it clear that popes are gods-on-earth and everyone knows that they can do anything ... again, without deigning to comment on magisterial texts I had cited.
I don't have to enable anything. Many blogs nowadays have given up accepting comments.
