That's a very, VERY broad brush you've got there Don. There have been divergent opinions expressed on this subject ... some of them well-thought out, many of them disagreeing with each other ... MOST of them not even mentioning the vessel captain.
I don't see this discussion in any way resembling a mob. I see it as a group of people wanting to express their views on a controversial action by a fellow diver.
Frankly, since you brought up the topic of self-righteousness ... your post is one of the most self-righteous I've seen in this thread. Basically you're telling people to either agree with you or shut up. I don't think discussion boards would be worth visiting if that attitude were to prevail.
