I have my doubts as to the effectiveness of sarcasm in his [Glenn's] writing...
We harbour no similar doubts as to the effectiveness of your writing, whether sarcastic, contrite, or otherwise, nor as to the substantive content therein. You might ask yourself why.... The answer to the first, I'd venture to say, has much to do with the answer to the second. Is that cleare enough for you?
Cheers,
