Apparently, even
the least offensive man I can think of off-hand can offend someone from time to time without even trying. Yet I can write intentionally controversial things and hardly get any backlash. It's a matter of readership volume, I guess. People being insulted is clearly the mark of success, because it proves that somebody was paying attention to you in the first place.
Also, my friend John nicely proved two things. First, that everybody responds to their critics sometimes. Second, that it's possible to do so without reducing the quality of your prose. Playful irony and sarcasm go a long way. Bravo, sir.
