Walter:
I don't see criticism of anything as trolling. Criticism involves reasons. If there are problems with PADI, DIR or anything else, those problems along with the reasoning behind them should never be considered trolling. OTOH, merely saying something is bad without explaining why you feel that way, especially if done so in an insulting manner, could be considered trolling.
I agree that criticism in and of itself isn't trolling. OTOH, criticizing in a manner that's meant to insult, demean, intimidate, or harrass is certainly trolling.
There's a whole lexicon of terms out there to describe various sorts of dive gear that are insulting, demeaning, or condescending. The only reason these exist (IMO) is to reinforce someone else's views of the "correct" kind of gear to use. That makes these terms not just unnecessary, but counterproductive to any form of meaningful dialogue. There may be valid reasons why someone thinks this gear is unsuitable ... but as soon as these colorful terms enter into the conversation, focus inevitably shifts from the logical to the emotional, and any validity to the POV is given short shift.
Good diving's not about the gear ... I keep hearing this ... often from the same people who are quick to point out perceived deficiencies in the gear other people are using.
For example, there's the "DIR Hall of Shame" ... it's sole purpose is to demean how other people dive ... and it's entire focus is on gear. It totally ignores all the fundamental tenets of what DIR is supposedly all about, of which the hardware is only one element. The very existence of this "DIR Hall of Shame" is, to my concern, nothing but a troll ... intended to demean people, some of whom are very good divers. It doesn't please me that the rig that I wear ... which I think is a very nice rig ... is pictured in this "Hall of Shame" (item # 11 last time I noticed). Nor does it please me to see a photo of one of my instructors ... an exceptionally good diver in my opinion and probably far more experienced than the people who created this Web site.
Stuff like this serves no purpose other than to give people reasons to want to "troll" back ... then the conversational focus shifts from substance to who can create the most verbal damage.
Perhaps, with respect to the Internet, DIR should stand for "Discussing it Right" ... I think that on both sides of the issue, conversation would be a lot more productive without the provocations that are incited by trivial things like a choice of terminology.
Unfortunately I think way too many people have forgotten that diving's supposed to be all about having fun (and not the kind one has at other people's expense) ... it never ceases to amaze me how uptight people can get over something as trivial as a recreational activity.
