"I agree that it is very unfortunate that he is ill but we are merely discussing his most recent role. "
Sorry, but this is bull****.
You used the phrases "weak and feeble", "one foot in the grave" and how (I paraphrase here) he wouldn't be missed if we were in a coffin. If you were remotely sincere about wishing him "the best", you wouldn't be posting at all. If you were less sincere but legitimately wanted to analyze his performance, you would find a way to do so without applying phrases that deliberately evoke death to a gentleman apparently fighting something very serious. Get some class, or stay off the boards.
