One thing that must be mentioned is that the terrain and quarry can dictate things to a degree. Where I hunt blacktail- and maybe someone like Jim in Oregon would concur, maybe not... anyway, the deer I kill are typically in very close quarters with me. 20-50 yards. Even the sound of the safety snicking off has alerted them to me before. So, point being, to chamber a round at that point would be very impractical- even if I was so inclined.
I think the people hunting in more open areas, where you might have almost unlimited time to set up a shot etc, should try to understand that things are real different in some other areas. If I was sitting on a hilltop glassing for miles... I could see how that guy might feel that it was not necessary to chamber a round.
Anyway, thanks for the civility, it's a breath of fresh air and, carry on!
