I know you were, and I am fully in agreement that there's alot of unnecessary impact made on the reefs at Cozumel by poor and/or inexperienced divers, and by irresponsible divemasters (or dive ops!) that do not hold their clients to strict standards. But it's really hard to know exactly what happened in this case just by someone's post. We see the post, we think of all the times that we've seen divers banging into corals, and we assume that this must be something like that. But, since we weren't there, it's impossible to know...now if the guy said, "and then I pried an anemone off the rock with my knife so I'd have a good handhold" or something like that, that's a real strong indication there's something bad going on.
BTW Gordon, I didn't mean to be snide in the rock comment; it's just that usually I agree with your posts, this time I had to take issue.
